Three friends A, B and C started a business by investing a total sum of ₹ 22,000. At the end of the year. A, B and C receives ₹ 900, ₹ 900 and ₹ 400 respectively as their profit share. What is the amount of capital invested by A, B and C?
Capital invested by A = ₹ 9000
Capital invested by B = ₹ 9000
Capital invested by C = ₹ 4000
Total amount invested = ₹ 22,000
Ratio of profits of A : B : C = 900 : 900 : 400 = 9 : 9 : 4
∵ the ratio of profit = 9 : 9 : 4
⇒ the ratio of investment should be 9 : 9 : 4.
Hence, capital invested by A = 22,000 × 99+9+4=22,000 × 922 =₹9000
Capital invested by B = 22,000 × 99+9+4=22,000 × 922 =₹9000
Capital invested by C = 22,000 × 49+9+4=22,000 × 422 =₹4000
