Pattern is: multiply the first number by 5 and then reverse the number thus obtained to get the second number.9 × 5 = 45, 9 + 54 = 63
7 × 5 = 35, 7 + 53 = 60
3 × 5 = 15, 3 + 51 = 54But,
8 × 5 = 40, 8 + 04 = 12 not 44, therefore, (8 : 44) is the odd one out.
Hence, option (D) is the correct response.
Logic:(4 x consecutive prime number)28 = 2 x 2 x 7 = 4 x 7
44 = 2 x 2 x 11 = 4 x 11
68 = 2 x 2 x 17 = 4 x 17
80 = 2 x 2 x 2 x 2 x 5 = 16 x 5 (odd one)
92 = 2 x 2 x 23 = 4 x 23
Hence, option C is the correct response.
The second word is the young form of first word.
As caterpillar is the young one of butterfly.
So, the odd word pair is insect : caterpillar.Hence, option C is the correct response.
Except 2873, all numbers are divisible by 7.
Hence, option(D) is different from others.
