Answer 2

The required "option (C) 35"​ is correct.

Step-by-step explanation:

We have,

12 : 30 : : 14 : ?

To find, the missing number = ?

The pattern follow:

× $\dfrac{5}{2}$

12 : 30

30 = 12 × $\dfrac{5}{2}$ = 6 × 5 = 30

Similarly,

14 : ?

? = 14 × $\dfrac{5}{2}$ = 7 × 5 = 35

∴ The missing number = 35

Thus, the required "option (C) 35"​ is correct.
