Q.If the ratio of the capital investments of A, B, and C is \(\cfrac{1}{2} : \cfrac{1}{3} : \cfrac{1}{4}\) and the total profit is ₹520, then C's share of the profit will be (a) ₹120 (b) ₹160 (c) ₹180 (d) ₹140
Answer: A
The ratio of A, B, and C's capital investments is \(\cfrac{1}{2} : \cfrac{1}{3} : \cfrac{1}{4}\)
= \(\cfrac{12}{2} : \cfrac{12}{3} : \cfrac{12}{4}\)
= 6 : 4 : 3
= \(\cfrac{6}{13} : \cfrac{4}{13} : \cfrac{3}{13}\) [∵ 6 + 4 + 3 = 13]
∴ C's share of the profit = \(\cfrac{3}{13}\) × ₹520
= ₹120.
