In the following question, four number pairs are given. In each pair the umber on the left side of (-) is related to the number on the right side of (-) with some Logic/Rule /Relation. Three pairs are similar on 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 numbers 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)
Answer & explanation
Correct answer: option 4
THE LOGIC;
1) 19 - 364,
19 x 2 + 3 = 364
2) 21 - 444,
21 x 2 + 3 = 444
3) 17 - 292,
17 x 2 + 3 = 293
4) 13 - 174,
13 x 13 + 3 = 172
Thus, 13 - 174 is the odd one.
