Question

Following a certain logic, 5 is related to 28 in the same way as 7 is related to 52 and 9 is related to 84. Using the same logic, to which of the following is 11 related?

A.

121

B.

124

C.

126

D.

128

Correct option is B

Given: 
5→28
7→52
9→84
Logic: The square of 1st number and + 3 = 2nd number.
52= 5 × 5 + 3 = 25 + 3 = 28
72= 7 × 7 + 3 = 49 + 3 = 52
92= 9 × 9 + 3 = 81 + 3 = 84
Applying the Formula to 11
112=11 × 11 + 3 = 121 + 3 = 124
Thus, the correct option is (B) 124.
