A, B and C entered into a partnership by making investment in the ratio 3 : 5 : 7. After a year C invests another Rs. 337600 while A withdraws Rs. 45600. The ratio of investments then changes to 14 : 29 : 167. How much did A invest initially?
Correct Answer: Rs. 233364.71
Explanation:
Let the initial investment of A, B, C be Rs. 3k, Rs. 5k and Rs. 7k respectivily.
Then, (3k - 45600) : 5k : (7k + 337600) = 14 : 59 : 167
⇒ (3k - 45600) / 5k = 14 / 29
⇒ k = 77788.24
∴ A investment initially Rs. (77788.24 x 3) = Rs. 233364.71
