Question
Below given are 2 wrong number series, where ‘x’ is
the correct replacement of the wrong term of series I & ‘y’ is the correct replacement of the wrong term of series II. Series I: 50, 57, 69, 84, 100, 118 Series II: 213, 109, 111, 168, 348, 843 I. 'y' is not a multiple of 'x'. II. Adding 24 to 'y' and then dividing the result by 'x+9' leaves a remainder of 45. III. The sum of the incorrect values is divisible by 12.Solution
ATQ, Series I 50 + 7 × 1 = 57 57 + 6 × 2 = 69 69 + 5 × 3 = 84 84 + 4 × 4 = 100 100 + 3 × 5 = 115 x = 115 Series II 213 × 0.5 + 2.5 = 109 109× 1 + 2 = 111 111 × 1.5 + 1.5 = 168 168× 2 + 1 = 337 337× 2.5 + 0.5 = 843 ‘y’ = 337 I. y/x = 337/115 (True) II. (y + 24)/(x + 9) = (337 + 24)/(115 + 9) = 361/124 (False) III.118 + 348 = 466  = 466/12 (False) Hence, Only I is correct
