Answer 1

Find work can be done by one man that's 1820 days. now,
28 men will do it in 65 days
And to finish it in 35 days you will need 52 men

Answer 2

Given

In 1 case

Men=13

Day =140


In 2 case

Men =28

Day=?

Using

M1D1 =M2D2

13x140=28xD2

D2=1820/28

D2=65days

Ans (1) 28 men can complete the work in 65 days

Now in 3 case days are given i.e. 35


Again using

M1D1 =M3D3=M2D2


Taking

M1D1 =M3D3

13x140=M3x35

M3=1820/35

M3=52

Ans(2)

To complete the work In 35 days 52 men required
