# On the basis of logical reasoning, find the correct option to replace ‘?’ in the table:

(a) 53

(b) 72

(c) 69

(d) 90

**Answer: (a) 53 **

**Explanation:-**

The square root of 169 = 13,

The square root of 121 = 11

The square root of 64 = 8 .

Then, 13 + 11 + 8

= 32,

The square root of 144 = 12,

The square root of 196 = 14,

The square root of 81 = 9.

Then, 12 + 14 + 9

= 35

Same as,

The square root of 289 = 17,

The square root of 441 = 21,

The square root of 225 = 15,

Then, 17 + 21 + 15

= 53

Then, the value of ? is 53.

Hence, the correct answer is option (a) 53.
