Answer» <P>After 6 months, P doubled his investment. ⇒ P invested Rs. 3500 for 6 months and Rs. 7000 for other 6 months. Q and R invested for only 4 months of the year. The ratio of PROFITS of P, Q, R and S = (6 × 3500 + 6 × 7000) : (4 × 3500) : (4 × 3500) : (12 × 3500) = 9 : 2 : 2 : 6 Q got a profit of Rs. 200. So, TOTAL profit = ((9 + 2 + 2 + 6)/2) × Rs. 200 = Rs. 1900 |
