Four number-pairs are given out of which three are alike in a certain way and one is different. Select the number-pair that is different from the rest.
Answer & explanation
Correct answer: option 1
The logic followed here is:
Ist number2 + ist number = second number
18 : 306 = 182 +18 = 342 ≠ 306(odd)
23 : 552 = 232 + 23 = 552
13 : 182 = 132 +13 = 182
25 : 650 = 252 + 25 = 650
