A can do a piece of work in 9 days and B can do the same work in 15 days. If they work together, in what ratio A and B will receive their wages?

A) 3 : 5

B) 5 : 3

C) 2 : 5

D) 5 : 2

Correct answer:
B) 5 : 3

Description for Correct answer:
A's 1 day's work = \( \Large \frac{1}{9} \)

B's 1 day's work = \( \Large \frac{1}{15} \)

A's share : B's share = \( \Large \frac{1}{9} : \frac{1}{15} \)

= \( \Large \frac{5}{45} : \frac{3}{45} \) = 5 : 3
