Answer» Correct Answer - Option 3 : Rs. 100 GIVEN: A can do half of the work in 5 days and B can do 1/3rd of the work in 6 days. CONCEPT: Efficiency is inversely proportional to time. And CALCULATION: Time in which A will complete the whole work = 5 × 2 = 10 days And Time in which B will complete the whole work = 6 × 3 = 18 days So, Ratio of efficiencies of A and B = 18 : 10 = 9 : 5 Hence, Amount received by B = 280 × 5/14 = Rs. 100 |
