Question

If 5 person can finish a job in 10 days then in how many days will 15 persons finish the same job?

Answer 1

Solution:

Given M1 = number of men 1 = 5
D1=number of days 1=10
M2=number of men 2 = 15
D2=number of days 2 = ?

Using relation: M1D1 = M2D2
5(10) = 15(D2)
50/15 = D2
so, D2 = 10/3 = 3(1/3) .
