Answer 2

Answer: 9 People (C)

Explanation:-

Remaining work =1/4

Remaining time = 8 days

Remaining time = 8 daysWork done by 36 persons in 1 day =1/40

Work done by 1 person in 1 day =1/36×40

Let the number of persons required to finish the remaining work be 'x'

Let the number of persons required to finish the remaining work be 'x'8×X×1/36×40=1/4

Or,X = 45

Number of additional persons required=45-36=9.
