Question

15 is related to 35 following a certain logic. Following the same logic, 21 is related to 49. To which of the given options is 27 related, following the same logic?
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)​​

A.

63

B.

69

C.

65

D.

51

Correct option is A

Given the relationships:
15 → 35
21 → 49
27 → ?
The following logic here is: (1st × 2) + (1st ÷\div 3) = 2nd Number 
15 → 35
(15×2)+(15 ÷ 3) 
= 30 + 5=35
21 → 49
(21 × 2) + (21 ÷ 3)
= 42 + 7 = 49
Applying the Pattern to 27 : ?
(27×2)+(27 ÷ 3)
= 54+ 9 = 63
Thus, the correct option is: (a)
