Question

if 40 men can finish a piece of work in 60 days in how many days will 75 men finish the same work

Answer 1

See,
40 mens can do the work in 60 days.
then
1 men can do the same work in = 40×60 days
=2400days
then we can find the no. of days required to finish the same work by 75 mens
=2400/75
=32days.

Answer 2

75 men finish the same work in 32 days.

Given: 40 men finish a work in 60 days and and then number of men increased to 75.

To Find: Days taken by 75 men to complete the work

Solution:

Initial number of men is 40

Days taken by thm to complete work = 60

Final number of men = 75

Then, M₁ × D₁=M₂ × D₂

40 × 60 = 75 × D₂

D₂ = 32 days

Hence, there are 32 days taken by 75 men to complete the work.
