Question
Three series are given below. You have to find the
values of P, Q and R, then establish a relationship among them. I:Â Â Â 210, P , 233, 64, 260, 35 II:Â Â Q , 66, 110, 170, 254, 370 III:Â Â 42, 54, 74, R , 146, 202Solution
ATQ, Series I, 210 - 112 = 89 89 + 122 = 233 233 - 132 = 64 64 + 142 = 260 260 - 152 = 35 A = 89 Series II, 66 - 30 = 36 110 - 66 = 44 (36 + 8) 170 - 110 = 60 (44 + 16) 254 - 170 = 84 (60 + 24) 370 - 254 = 116 (84 + 32) B = 30 Series III, 42 + 3 × 4 = 54 54 + 4 × 5 = 74 74 + 5 × 6 = 104 104 + 6 × 7 = 146 146 + 7 × 8 = 202 C = 104 Of all given options, these values fit in option C i.e., A + B = C + 15 = 98 + 30 = 128 = 104 + 15Â
