Answer 1

✨Answer:

✔️Your answer is "6".

✨Step-by-step explanation:

121 : 12 :: 25 :?

➡️ We see,

In first relation :

121 = (11) ^2

12 = 11 + 1

➡️ So the rule is :

(n) ^2 : n + 1.

Applying this rule to second relation :

25 = (5)^2

➡️ Therefore, "n" here = 5.

➡️ n + 1 = 5 + 1 = 6

✔️So required no is 6.

.

Hence, answer is 6 or,

OPTION [C] 6.
