Question
Four number-pairs are given, three of them are alike in
a certain manner and one is different. Choose the different number-pair.Solution
The product of digits of first number is divided by 2 to obtain second number. In option (a): 926: 54 (9 × 2 × 6) = 108, (108 ÷ 2) = 54 In option (b): 772: 49 (7 × 7 × 2) = 98, (98 ÷ 2) = 49 In option (c): 522: 10 (5 × 2 × 2) = 20, (20 ÷ 2) = 10 In option (d): 463: 32 (4 × 6 × 3) = 72, (72 ÷ 2) = 36 ≠ 32
