Question

In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number Which numbers should replace X and Y so that the pattern followed by the two numbers on the left side of :: is the same as that on the right side of :: ?

X : 125 :: 13 : Y

A.

X = 12 , Y = 173

X = 11 , Y = 173

C.

X = 11 , Y = 169

D.

X = 12 , Y = 169

Correct option is B

Given: X : 125 :: 13 : Y

Logic: Square of 1st + 4 = second. 

Form the option (b) X = 11 , Y = 173

112+4=121+4=125 132+4=169+4=17311^2 + 4 = 121+4 = 125 \\ \ \\ 13^2 + 4 = 169 + 4 = 173
