Question

12:35::16:? a.62 b.53 c.40 d.63 e.64​

Answer 1

The required "option d) 63" is correct.

Step-by-step explanation:

We have,

12 : 35 : : 16 : ?

To find, the missing number = ?

The pattern follow:

$\dfrac{x}{2} : (\dfrac{x}{2})^2-1$

12 : 35

12 = $(\dfrac{12}{2})^2-1=6^{2} -1=36-1=35$

Similarly,

?  $= (\dfrac{16}{2})^2-1=8^{2} -1=64-1=63$

∴ The missing number(?) = 63

Thus, the required "option d) 63" is correct.
