Question
A, B and C started a online education website by
investing Rs.36,000, Rs.40,000 and Rs.50,000 respectively. Find the share of A’s, out of an annual profit of Rs.12600.Solution
Ratio of shares of A, B and C = Ratio of their investments = 36000: 40000: 50000 ⇒ 18 : 20 : 25 Therefore, A’s share = Rs {12600 × 18/63} = Rs. 3600
