Select the option that is related to the fourth term in the same way as the first term is related to the second term and the fifth term is related to the sixth term.
70 : 625 :: ? : 144 :: 37 : 196

Logic: square root of second number is multiplied by 3 and 5 is subtracted in the resultant to get first number.

As,

70 : 625

√625 × 3 – 5 = 25× 3 – 5 = 75 -5 = 70

And

37 : 196

√196 × 3 – 5 = 14× 3 – 5 = 42 -5 = 37

Similarly,

? : 144

√144 × 3 – 5 = 12× 3 – 5 = 36 -5 = 31
