A) 7 days

B) 8 days

C) 10 days

D) 12 days

Correct Answer:
C) 10 days

Description for Correct answer:

Let the work done be 1 work.

Here, M1 = 15

D1 = 16

W1 = W2 = 1

M2 = 24

D2 = ?

According to the formula, M1D1W2 = M2D2 W1

15 x 16 x 1 = 24 x D2 X 1

D1 =\( \Large\frac{ 15 \times 16 }{24} = 10\)

Therefore, 10 days are required to complete, the work.
