Select the option that is related to the third number in the same way as the second number is related to the first number and the sixth number is related to the fifth number.

5 : 50 : : 6 : ? : : 12 : 288

72

5 : 50 : : 6 : ? : : 12 : 288

The logic followed here is :

(Ist number )²  × 2 = IInd number

AS

(5)²  × 2

25 × 2  = 50

and

(12)²  × 2

144 × 2  = 288

Same as

(6)²  × 2

36 × 2  = 72
