For the following questions answer them individually

Q. 51 The time taken by a boat to travel 13 km downstream is the same as time taken by it to travel 7 km upstream. If the speed of the stream is 3 km/h, then how much time (in hours) will it take to travel a distance of 44.8 km in still water?

A. 412/25

B. 53/5

C. 52/5

D. 413/25

Explanation:

Speed of the stream = 3 km/h

Let the speed of the boat be v.

Speed in downstream = 3 + v

Speed in upstream = v – 3

Time = distance/speed

According to the question,

The time taken by a boat to travel 13 km downstream = time taken by boat to travel 7 km upstream

13/(3 + v) = 7/(v – 3)

13v – 39 = 21 + 7v

6v = 60

v = 10 km/h

Speed of boat = 10 km/h

The time taken by a boat to travel a distance of 44.8 km in still water = 44.8/10 = 112/25 = 412/25hr

Q. 53 In PQR, ∠Q = 85and R = 65. Points S and T are on the sides PQ and PR, respectively such that STR = 95, and the ratio of the QR and ST is 9 : 5. If PQ = 21.6 cm, then the length of PT is:

A. 10.5 cm

B. 9.6 cm

C. 12 cm

D. 9 cm

Explanation:

PTS + ∠STR = 180

PTS = 180− 95= 85

△PTS is similar to △PQR So,

( ∠P is common and ∠PTS = ∠SQR  )

ST / QR = PT/PQ

(QR : ST = 9 : 5 and PQ = 21.6 cm)

5 / 9 = PT/21.6

21.6 × 5 = PT × 9

PT = 108/9 = 12 cm

∴ The length of PT is 12 cm.

Q. 54 If 30x2 − 15x + 1 = 0, then what is the value of  25x2 + (36x2) −1

A. 9/2

B. 6 ¼

C. 65/12

D. 55/12

Explanation:

30x2 − 15x + 1 = 0

Dividing by x,

30x − 15 + 1/x = 0

5x − 15/6 + 1/6x

5x + 1/6= 5/2

taking square both side,

(5x + 1/6x)2  = (5/2)

25x2 + 1/36x2 + 2 × 5x × 1/6x = 25/4

25x2 + 1/36x2 = 25/4 – 5/3

25x2 + 1/36x2 = 55/12

Q. 55 The income of A is 60% less than that of B, and the expenditure of A is equal to 60%of B’s expenditure. If A’s income is equal to 70% of B’s expenditure, then what is the ratio of the savings of A and B?

A. 3 : 8

B. 5 : 9

C. 4 : 7

D. 2 : 15

Explanation:

Let the income of B be 100.

Income of A = 100×40/100 = 40

A’s income is equal to 70% of B’s expenditure so,

40 = 70% of B’s expenditure

Expenditure of B = 40/70×100 = 400/7

Saving of B = 100 – 400/7 = 300/7

The expenditure of A is equal to 60%of B’s expenditure so,

Expenditure of A = 60% of B’s expenditure

Expenditure of A = 60× 400/(7×100) = 240/7

Saving of A. = 40 – 240/7 = 40/7

The ratio of the savings of A and B = 40/7 : 300/7 = 2 : 15

Q. 56 The value of is:

Q. 57 A cylindrical vessel of radius 30 cm and height 42 cm is full of water. Its contents are emptied into a rectangular tub of length 75 cm and breadth 44 cm. The height (in cm) to which the water rises in the tub is: (Take π = 22/7

A. 36

B. 30

C. 40

D. 45

Explanation:

Volume of the cylindrical vessel = πr2h = 22/7 × 302 × 42 = 118800

If we replace the water from the cylindrical vessel to rectangular tub then volume should be equal of the cylindrical vessel rectangular tub.

Volume of the cylindrical vessel = Volume of rectangular tub

118800 = length ×breadth × height

118800 = 75 × 44 × height

Height = 118800/3300 = 36 cm

Q. 58 The given table represents the revenue (in ₹ crores) of a company from the sale of four products A B C and D in 6 years. Study the table carefully and answer the question that follows.

A. 18

B. 25

C. 28

D. 20

Explanation:

Total revenue of the company from the sale of products B, C and D in 2014 = 92 + 96 + 92 = 280

Total revenue from the sale of products C. and D. in 6 years = 82 + 76 + 98 + 102 + 96 + 92 + 88 +93 + 93 + 97 + 103 + 102 = 1120

Required percentage =280/1120 ×100 = 25%

Q. 59 If 7 sin2  θ − cos2 θ + 2 sin θ = 2, 0< θ < 90, then the value of (sec 2θ+cot 2θ)/(cosec 2θ+tan 2θ) is:

A. (2√3+1)/ 3

B.

C. ⅕ (1+2√3)

D. ⅖ (1+√3)

Explanation:

7 sin2 θ − cos2 θ + 2 sin θ = 2

⇒ 7 sin2 θ  cos2 θ + 2 sin θ − 2 = 0

⇒ 7 sin2 θ − (1 − sin2 θ) +2 sin θ − 2 = 0

⇒ 8 sin2  θ + 2 sin θ − 3 = 0

⇒ 8 sin2 θ + 6 sin θ − 4 sin θ − 3 = 0

⇒ 2 sin θ(4 sin θ + 3) − 1(4 sin θ + 3) = 0

⇒ (2 sin θ − 1)(4 sin θ + 3) = 0

0< θ < 90

For ,

2 sin θ − 1=0

θ = sin-1(1/2)

θ = 30°

(sec 2×30°+cot 2×30°)/(cosec 2×30°+tan 2×30°)

Q. 60 The ratio of boys and girls in a group is 7 : 6. If 4 more boys join the group and 3 girls leave the group, then the ratio of boys to girls becomes 4 : 3. What is the total number of boys and girls initially in the group?

A. 117

B. 78

C. 91

D. 104

Explanation:

The ratio of boys and girls in a group is 7 : 6.

Let the boys be 7x and girls be 6x.

When 4 more boys join the group and 3 girls leave the group, then the ratio of boys to girls = 4 : 3

(7x+4)/(6x−3) = 4/3

21x + 12 = 24x -12

3x = 24

x = 8

Initially boys and girls = 7x + 6x = 13x = 13×8 = 104

Q. 61 The difference in compound interest on a certain sum at 10% p.a. for one year, when the interest is compounded half yearly and yearly, is ₹88.80. What is the simple interest on the same sum for 1⅔ years at the same rate?

A. ₹5,916

B. ₹5,986

C. ₹5,980

D. ₹5,920

Explanation:

Principal = p

Rate(r) = 10%

Time(t) = 1 year

compound interest = p(1 + r/100)t p

When interest is calculated yearly = p(1 + 10/100) − p = p × (110/100) − p

When interest is calculated half yearly,

Rate(r) = 10/2 = 5%

Time(t) = 1×2 = 2

Interest = p(1 + 5/100)2 – p = p(105/100)2 – p

Difference of interest = 88.80

p × (105/100) × (105/100) − p p × (110/100) + p = 88.80

p × 1.05 × 105 − p × 110 = 8880

110.25p – 110p = 8880

p = 8880/.25 = 35520

Simple interest for 1⅔ years,

t =1⅔ = 5/3 years

Interest =prt/100 = (35520 ×10 ×5/3)/100

= Rs.5920

Q. 62 The expression 3 sec2 θ tan2 θ + tan6 θ − sec6 θ is equal to:

A. -2

B.

C.

D. -1

Explanation:

3 sec2 θ tan2 θ + tan6 θ − sec6 θ

= −3 sec2 θ tan2 θ(tan2 θ − sec2 θ) + tan6 θ − sec6 θ

(∵ tan2 θ − sec2 θ = −1)

= (tan2 θ − sec2 θ )3

( ∵ (a b)3 = a3 b3 − 3ab(a b) )

=(−1)3 = -1

Q. 63 One-third of goods are sold at a 15% profit. 25% of the goods are sold at a 20% profit and the rest at a 20% loss. If the total profit of ₹138.50 is earned on the whole transaction, then the value(in ₹) of the goods is:

A. ₹8,587

B. ₹8,030

C. ₹7,756

D. ₹8,310

Explanation:

Let the total goods be 300

One third, means 100 goods are sold at 15℅ profit

25℅ means 75 goods are sold at 20℅ profit

The rest, means 125 goods are 20℅ loss

Let the price of each good be Re. 1

So, now calculating the profit and loss amounts:

For 100 goods, profit is 15℅ = Rs. 115

For 75 goods, profit is 20℅ = Rs. 90

For 125 goods, loss is 20℅ = Rs. 100

So, total amount of the selling price= Rs. 305

Total cost price = Rs.300

So, the profit = Selling price- cost price = Rs. 305-300 = Rs.5

Now equating it to the real values:

Rs. 5 is the profit when the total amount of goods is Rs 300.

Rs. 138.50 is the profit when total amount of goods is= (300/5)*138.5 = Rs. 8310

∴ The value of the goods is Rs. 8310.

Q. 64 The given table represents the revenue (in ₹ crores) of a company from the sale of four products A B C and D in 6 years. Study the table carefully and answer the question that follows.

What is the ratio of the total revenue of the company in 2014 from the sale of all the four products to the total revenue from the sale of product C in 2014 to 2017?

A. 14 : 23

B. 18 : 19

C. 7 : 10

D. 7 : 9

Explanation:

Total revenue of the company in 2014 from the sale = 80 + 92 + 96 + 92 = 360

The total revenue from the sale of product C. in 2014 to 2017 = 96 + 88 + 93 + 103 = 380

The ratio of the total revenue of the company in 2014 from the sale of all the four products to the total revenue from the sale of product C. in 2014 to 2017 = 360 : 380

= 18 : 19

Q. 65 If the 6-digit numbers x35624 and 1257y4 are divisible by 11 and 12, respectively, then what is the value of (5x – 2y ) ?

A. 26

B. 12

C. 10

D. 13

Explanation:

Divisibility rule of 11,

The sum of of alternative digit are equal so,

x + 5 + 2 = 3 + 6 + 4

x = 6

B. 472

C. 463

D. 479

Explanation:

We know that,

a3 + b3 + c3 − 3abc = (a + b + c)(a2 + b2 + c2 − (ab + bc + ac))

a + b + c = 7

Squaring both sides,

(a + b + c)2 = 49

a2 + b2 + c2 + 2(ab + bc + ac) = 49

a2 + b2 + c2 = 49 + 12 = 61

a3 + b3 + c3 − 3abc = (a + b + c)(a2 + b2 + c2 − (ab + bc + ac))

= 7(61 – (-6)) = 7× 67 = 469

Q. 67 The given table represents the revenue (in ₹ crores) of a company from the sale of four products A, B, C and D in 6 years. Study the table carefully and answer the question that follows.

By what percentage is the total revenue of the company from the sale of products A, B and D in 2012 and 2013 more than the total revenue from the sale of product B in 2013 to 2016? (Correct to one decimal place)

A. 44.5

B. 31.2

C. 43.6

D. 45.4

Explanation:

Total revenue of the company from the sale of products A, B. and D. in 2012 and 2013 = 98 + 74 + 74 + 94 + 96 + 102 = 538 Total revenue from the sale of product B. in 2013 to 2016 = 96 + 92 + 84 + 98 = 370

Required percentage =(538−370)/370 × 100 = 45.4%

Q. 68 A and B, working together, can complete a work in d days. Working alone, A takes (8 + d) days and B. takes (18 + d) days to complete the same work. A work for 4 days. The remaining work will be completed by B alone, in:

A. 24 days

B. 16 days

C. 18 days

D. 20 days

Explanation:

To find the time when A and B,

working together = √(moredaystakenbyA × moredaystakenbyB )

d = 12

Time taken by A to complete the work = (8 + d) = 8 + 12 = 20

Time taken by B to complete the work = (18 + d) = 18 + 12 = 30 Let the total work be 60.

(LCM of 20 and 30 is 60.)

Efficiency of A = 60/20 = 3

Efficiency of B = 60/30 = 2

Work done by A in 4 days = efficiency 3× 4 = 12days

Remaining work = 60 – 12 = 48

Time taken by B to complete the remaining work = 48/2 = 24 days

The remaining work will be completed by B alone, in 24 days.

Q. 69 Two chords AB and CD of a circle are produced to intersect each other at a point P outside the circle. If AB = 7 cm, BP = 4.2 cm and PD = 2.8 cm, then the length of CD is:

A. 12 cm

B. 14.6 cm

C. 15.8 cm

D. 14 cm

Explanation:

AB = 7 cm, BP = 4.2 cm and PD = 2.8 cm

By the property,

PA×PB = PC× PD

(PA = AB + BP = 7 + 4.2 = 11.2 cm)

11.2 × 4.2 = PC × 2.8

PC = 16.8 cm

CD = PC – PD = 16.8 – 2.8 = 14 cm

Q. 70 The value of{tan2θ – sin2θ}{2 + tan2θ + cot2θ} is:

A. cosec6θ

B. cos4θ

C. sin6θ

D. sec4θ

Explanation:

{tan2θ – sin2θ}{2 + tan2θ + cot2θ

={tan2θ – sin2θ}{1 + tan2θ + 1 + cot2θ

={tan2θ – sin2θ}{sec2θ + cosec2θ

={tan2θ – sin2θ}{1/cos2θ +1/sin2θ

={(tan2θ – sin2θ)(sin2θ cos2θ)}{cos2θ + sin2θ}

= (tan2θ – sin2θ)(sin2θcos2θ)

= sin4θ – sin4θ cos2θ

= sin4θ(1 – cos2θ) = sin4θ sin2θ = sin6θ

Q. 71 In ΔABC, D and E are the points on sides AC and BC, respectively, such that DE is parallel to AB. F is a point on CE such that DF CE. If CE = 6 cm, and CF = 2.5 cm, then BC is equal to:

Q. 73 The average weight of some students in a class was 58.4 kg. When 5 students having the average weight 62.8 kg joined the class, the average weight of all students in the class increased by 0.55 kg. The number of students initially in the class, were:

A. 30

B. 35

C. 25

D. 40

Explanation:

The average weight of some students in a class = 58.4 kg

Let the total number of students be n.

Total weight of n students = 58.4n kg

The average weight of 5 students = 62.8 kg

Total weight of 5 students = 62.8 × 5 = 314 kg

The average weight of (n + 5) students = 58.4 + 0.55 = 58.95 kg

Total weight of (n + 5) students = 58.95(n + 5) kg

Total weight of n students + Total weight of 5 students = 58.95(n + 5)

58.4n + 314 = 58.95(n + 5)

58.4n + 314 = 58.95n + 294.75

0.55n = 19.25

n = 1925/55 = 35

∴ 35 students were initially in the class.

Q. 74 PRT is a tangent to a circle with centre O, at the point R on it. Diameter SQ of the circle is produced to meet the tangent at P and QRis joined. If QRP = 280, then the measure of SPR is:

A. 290

B. 340

C. 620

D. 320

Explanation:

∠QRP = 280

∠ORP = 900 (radius to tangent through PT of contact)

∠QRO = ∠ORP – ∠QRP

∠QRO = 900 – 280 = 620

Now,

∠QRO = ∠OQR

∠OQR = 620

∠RQP + ∠OQR = 1800

∠RQP = 1800 – 620 = 1180

In the ΔOPR,

∠SPR + ∠RQP + ∠QRP = 1800

∠SPR = 1800 – 1180 – 280 = 340

Q. 75 If P ={x4 – 8x}/{x3 – x2 – 2x}, Q ={x2 + 2x + 1}/{x2 – 4x – 5} and R ={2x2 + 4x + 8}{x – 5}, then (P×Q) ÷ R is equal to:

A. ½
