Show answer & explanation

Correct answer: C

Solution:

Step 1: Compute each person's work rate (work done per day).

  • A's rate = 1/10 work per day.

  • B's rate = 1/15 work per day.

Step 2: Find the ratio of the work done by A to B.

Work ratio = (1/10) : (1/15) = 3 : 2.

Step 3: Divide the total wages in the same ratio.

A's share = 3 / (3 + 2) × 75 = 3/5 × 75 = Rs. 45.

Therefore, A will get Rs. 45.
