15 men complete a work in 16 days If 24 men are employed then the time require to complete that work will be

let the work done be 1 work.
Here M1=15, D1=16 W1=W2 =1
M2 =24 D2= ?
∴ According to the formula
M1 D1 W2 = M2 D2 W1
⇒ 15 x 16 x 1 = 24 x D2 X 1
∴ D1 = 15 X 16/24 = 10
Therefore 10 days are required to complete the work
