Three of the following numbers are alike in a certain way and one is different. Pick the odd one out. a) 90 – 144, b) 45 – 70, c) 65 – 104, d) 75

Three of the following numbers are alike in a certain way and one is different. Pick the odd one out.

(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 /deleting /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.

Options
a) 90 – 144
b) 45 – 70
c) 65 – 104
d) 75 – 120

Solution

As per solution
Logic :- Divide 2nd number by first Number
$\frac {144}{90} = 1.6$
$\frac {70}{45} = 1.5$
$\frac {104}{65} = 1.6$
$\frac {120}{75} = 1.6$
In three cases result is 1.6 and in case of b) 45 – 70 result is 1.5
Therefore b) 45 – 70 is different.

Ans is ) 45 – 70

Three of the following numbers are alike in a certain way and one is different. Pick the odd one out.
