Question
A, B and C started a business. Twice the investment of A
is equal to thrice the investment of B and also five times the investment of C. If the total profit after a year is ₹ 15.5 lakhs, then the share of B in the profit is (in ₹ lakhs):Solution
2A = 3B = 5C L.C.M of 2, 3 and 5 = 30 So, A = 30/2 = 15 ⇒ B = 30/3 = 10 ⇒ C = 30/5 = 6 Total profit = 15 + 10 + 6 = 31 Share of B = (10/31) × 15.5 lakhs ⇒ Rs. 5 lakhs ∴ The share of B is Rs. 5 lakhs
