Description for Correct answer:
A's 1 day's work = \( \Large \frac{1}{3} \)

B's 1 day's work = \( \Large \frac{1}{2} \)

A's share : B's share = \( \Large \frac{1}{3} \) : \( \Large \frac{1}{2} \)

= \( \Large \frac{2}{6} \) : \( \Large \frac{3}{6} \) = 2 : 3

Share of A = \( \Large \frac{2}{5} \times 225 \) = Rs.90
