Let A and B invested Rs. x each in the business at the starting and as given, C invested Rs. 3.5

Lakhs.

Since A invested for 12 months, B invested for 8 months and C invested for 8 months.

⇒ Ratio in which profit would be shared = (x × 12) ? (x × 8) ? (3.5 × 8) = 3x ? 2x ? 7

Now given total profit is Rs. 62400 and profit share of A is Rs. 24000,

⇒ 3x/ (5x + 7) = 24000/62400

⇒ 3x/ (5x + 7) = 5/13

⇒ 39x = 25x + 35

⇒ 14x = 35

⇒ x = 5/2 = 2.5 lakhs

∴ Share of C = [7/ (12.5 + 7)] × 62400 = Rs. 22400
