Question
A, B and C are in partnership. A's capital was ₹ 65,000, C's capital was ₹ 50,000. The total profit is ₹ 38,000, out of which B's profit is ₹ 15,000. What was B's capital ?
Solution
Let B's capital (in thousand) = x
∴ 65 : x : 50 is the ratio of A, B, C's investment
∴ Ratio of profit is also 65 : x : 50
Total profit -= ₹ 38,000
`therefore "x"/(65 + "x" + 50) xx 38000 = 15000`
`therefore "38x"/(115 + "x") = 15`
38x = 15 x 115 + 15x
∴ 23x = 15 x 115
`therefore "x" = (15 xx 115)/23 = 75`
∵ x is in thousand,
∴ B's capital is ₹ 75,000
