Ramesh, Rajan and Ritesh enter into partnership by making investments in the ratio 3 : 5 : 7. After a year, Ritesh invests another Rs. 337600 while Ramesh withdraws Rs. 45600. The ratio of investments then changes to 24:59:167. How much did Ramesh invest initially?
Let the initial investments of Ramesh, Rajan, Ritesh be Rs. 3x, 5x and 7x respectively. => (3x – 45600) : 5x : (7x + 337600) = 24:59:167 => (3x – 45600)/5x = 24/59 => x = 47200 ∴ Ramesh initially invested Rs. (47200 × 3) = Rs. 141600
