Question
Three series are given below. You have to find the
values of P, Q and R, then establish a relationship among them. I: 840, P , 584, 456, 520, 488 II: 750, 21, 264, ( P/2 + 19), 210, Q III: 225, 250, Q , 282, 161, RSolution
ATQ, Series (i), 840 – 29 = 328 328 + 28 = 584 584 – 27 = 456 456 + 26 = 520 520 – 25 = 488 P = 328 Series (ii), (P/2) + 19 = (328/2) + 19 = 164 + 19 = 183 750 – 36 = 21 21 + 35 = 264 264 – 34 = 183 183 + 33 = 210 210 – 32 = 201 Q = 201 Series (iii), 225 + 52 = 250 250 – 72= 201 201 + 92 = 282 282 – 112 = 161 161 + 132 = 330 R = 330 Thus, R > P > Q.
