Question
A sum of money is divided among P, Q, R and S in the
ratio of 2:3:9:10 respectively. If the share of R's is Rs. 3900 more than the share of Q, then what is the total amount of money of P and S together?Solution
Ratio of P, Q, R and S is 2:3:9:10 respectively, According to the question, Â => R = 3900 + 3x => 9x = 3900 + 3x => 6x = 3900 => x = 650 => Total amount of P and S together = 2x + 10x = 12x = 12 x 650 = Rs. 7800
