Question

if 13 mens can do a work in 140 days in how many days 28 men will do it how many mens are required to complete the work in 35 days

Answer 1

HEY DEAR ...

13 men can complete a work in 140 days.
1 man can complete a work in (140 × 13) = 1820 days.
28 men can complete a work in (1820/28) = 65 days
Let the no. of men required to complete the work in 35 days be x
x men can complete a work in 35 days.
ATQ,
1820/x = 35
x = 1820/35 = 52
Hence, 52 men can complete a work in 35 days.
