$A, B$ and $C$ completed a work costing ₹ 1800. A worked for 6 days, $B$ for 4 days and $C$ for 9 days. If their daily wages are in the ratio of 5 : 6 : 4, how much amount will be received by $A$ ?
(a)₹ 600
(b)₹ 750
(c)₹ 800
(d)₹ 900
Answer
Answer (as printed): A
Explanation
Let the daily wages of A, B and C be $₹5x$, $₹6x$ and $₹4x$ respectively. Then, ratio of their amounts $=(5x \times 6):(6x \times 4):(4x \times 9)=30:24:36=5:4:6$. $\therefore$ A's amount $=₹\left(1800 \times \frac{5}{15}\right)=₹600$.
