Question

Study the given pattern carefully and select the number that can replace the question mark (?) in it.

121	64	144
27	?	8
14	12	14

1. 64
2. 49
3. 56
4. 72

Answer 1

Correct Answer - Option 1 : 64

The logic follows here is:

In column-wise operation,

The sum of square root of first number + cube-root of second number = third number

In column 1:

√ 121 + ∛ 27 = 14

11 + 3 = 14

14 = 14

In column 2:

√ 64 + ∛ ? = 12

8 + ∛ ? = 12

∛ ? = 12 - 8

∛ ? = 4

? = 4³

? = 64

In column 3:

√ 144 + ∛ 8 = 14

12 + 2 = 14

14 = 14 

Hence, the correct answer is "64".
