Question : Directions: Four number pairs have been given out of which three are alike in some manner and one is different. Select a different one.

E.g. 13 – operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Correct Answer: 32 : 201
Solution :
Let's check the given options –
First option:
16 : 90; (16 × 6) – 6 = 96 – 6 = 90
Second option:
41 : 240; (41 × 6) – 6 = 246 – 6 = 240
Third option:
21 : 120; (21 × 6) – 6 = 126 – 6 = 120
Fourth option:
32 : 201; (32 × 6) – 6 = 192 – 6 = 186
≠
201
So, only the fourth option does not follow the pattern of the other three options. Hence, the fourth option is correct.
