Question
Given below are two number series I and II where each
series has a wrong (odd one out) number. The number that will actually come in place of the wrong number in series I and II are 'P' and 'Q' respectively. Find which among the given options gives the correct sum of 'P' and 'Q'. I: -20, -57, -68, -53, -10, 49 II: 30, 55, 120, 240, 436, 725Solution
So, -12 should come in place of -10 So, P = -12 For series II: 30 + 52Â = 55 55 + 82Â = 119 119 + 112Â = 240 240 + 142Â = 436 436 + 172Â = 725 Therefore, 119 should come in place of 120. So, Q = 119 Sum of P and Q = 119 + (-12) = 107 Â
