Answer 1

Answer:

D) 1000

Step-by-step explanation:

Robin’s 1 day work = 1/9

Amit’s 1 day work = 1/6

When they work together, they received Rs. 2500

? Ratio of wages = Ratio of work efficiencies

⇒ Robin’s share? Amit’s share = (1/9) ? (1/6) = 6 ? 9 = 2 ? 3

Sum of ratios = 2 + 3 = 5

∴ Robin’s share = 2/5 × 2500 = Rs. 1000
