In the following question, four number pairs are given. In each pair the number on left side of (–) is related to the number of the right side of (–) with some Logic/Rule/Relation. Three pairs are similar on the basis of same Logic/Rule/Relation. Select the odd one out from the given alternatives.
(NOTE: Operations should be performed on the whole numbers, without breaking down the number into its constituent digits. 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)
Show answer & explanation
Correct answer: D
Explanation
Pattern
Second number = (First number)2
Check:
1) 13 – 169
132=169
2) 12 – 144
122=144
3) 11 - 121
112=121
4) 10 - 110
102=100
Should be = 100
But given is 110
So it does not follow the pattern.
Correct answer: 4) 10 – 110
