30 men working 8 hours per day can dig a pond in 16 days. By working how many hours per day can 32 men dig the same ponds in 20 days?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e 6 hours per day.

Understanding Application

M1 x T1 x D1 = M2 x T2 x D2

M = Number of men

T = Per day working hours

D = Days 

30 x 8 x 16 = 32 x T2 x 20

T2=(30 x 8 x 16)/(32 x 20)

=(3 x 4)/(2) 

= 6 hours
