6 boys can complete a piece of work in 16 h. In how many hours will 8 boys complete the same work?


A) 10

B) 8

C) 12

D) 14

Correct Answer:
C) 12

Description for Correct answer:

Given, M1 = 6

M2 = 8

T1 = 16 h

T2 = ?

W1 = W2 = 1

According to the formula,

M1 T1 W2 = M2 T2 W1

.6 x 16 x 1 = 8 X T2 X 1

T2 = \( \Large\frac{16 \times 6}{8} = 2 \times 6 = 12h \)
