Question

A job takes 30 men for 15 days to complete. How many men need to increase to do the same job in 10 days?

Answer 1

45 days

Explanation:

30men=15days

1man=15×30

1man=450days

10men=450÷10

10men=45days

I think that's it

Answer 2

45 men

Explanation:

A job takes 30 men for 15 days to complete so it takes x men to do the same job in 10 days

30(15) = x(10)

450 = 10x

x = 450/10

x = 45
