Question 64

A can do a work in 12 days while B can do it in 15 days. They undertake to complete it together for Rs. 450. what will be the share of A in this amount of money ?

Solution

Let total work to be done = 60 units

A can do the work in 12 days.

=> A's efficiency = $$\frac{60}{12}=5$$ units/day

Similarly, B's efficiency = $$\frac{60}{15}=4$$ units/day

Total amount = Rs. 450

$$\therefore$$ A's share of money = $$\frac{5}{(5+4)} \times 450$$

= $$5 \times 50=Rs.$$ $$250$$

=> Ans - (C)
