Correct Answer - Option 2 : 2 ∶ 3
Given:
A earns Rs. 120 per hour and works for 5 hours per day.
B earns Rs. 150 per hour and works for 6 hours per day.
Calculation:
A one day wages = 120 × 5 = Rs. 600
B one day wages = 150 × 6 = Rs. 900
According to the question,
The ratio of their wages,
A ∶ B = 600 ∶ 900
A ∶ B = 2 ∶ 3
∴ The ratio of their wages A and B is 2 ∶ 3.
