An amount of Rs.1,000 is to be distributed amongst P, Q, R and S such that “P” gets twice as that of “Q” and “S” gets four times as that of “R”. If “Q” and “R” are to receive equal amount, what is the difference between the amounts received by S and P?
[ "A)2378", "B)2697", "C)250", "D)5000" ]
C
Explanation: We have, P = 2Q & S = 4R Further Q = R & P + Q + R + S = 1,000 Thus we get, 2Q + Q + Q + 4Q = 1,000 8Q = 1,000 or Q = Rs. 125 Thus, R = Rs. 125, P = 250 & S = Rs. 500 Hence, the required difference = (S – P) = (500 – 250) = Rs.250 ANSWER:C
