Question
Four number-pairs are given, out of which three are
alike in a certain manner and one is different. Choose the different number-pair.Solution
The pattern followed here is: The square of each digit of the first number is added together, and the result is multiplied by 2 to obtain the code. 345: 100 β 2 X (3Β² + 4Β² + 5Β²) = 2 X (9 + 16 + 25) = 2 X 50 = 100 284 : 168 β 2 X (2Β² + 8Β² + 4Β²) = 2 X (4 + 64 + 16) = 2 X 84 = 168 562 : 130 β 2 X (5Β² + 6Β² + 2Β²) = 2 X (25 + 36 + 4) = 2 X 65 = 130 693 : 252 β 2 X (6Β² + 9Β² + 3Β²) = 2 X (36 + 81 + 9) = 2 X 126 = 252
β64 of β225 = β(25 + ?) X 12
√4761 ÷ 23 + √12769 = ? × 58
((8)0- (0.1)-1)/( (6/16)-1 ×(3/2)3+ ((-2)/6)-1) = ?/2
(1/3) + (2/5) + (3/4) + (11/10) = 3 β (?/12)
(1225/25) - (192/96) + (50/5) = ?
84% of 8400 + 42% of 6120 =?
4387897 – 3286871 – 51926 = ?
