A. 12

B. 13

C. 15

D. 16

After 6 days four workers left. So the number of people working is 44

Total number of days required for 44 men to complete the remaining work = 528/44 =12

A. 50

B. 30

C. 50.5

D. 45

Answer: A

The median of the number = (n+1)/2 = 22/2 = 11th number

Given that the observations greater than median i.e 11th number is increased by 21. There are 10 observations like that.

Total sum becomes 840 + 210 = 1050

The new mean will be 1050/21 = 50
