11 is related to 77 following a certain logic. Following the same logic, 16 is related to 112.
To which of the following is 21 related, following the same logic?
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
Answer & Solution
Correct option is B
The logic followed here is:
Logic: 1st number × 7 = 2nd number.
Now,
For, 11 : 77
=> 11 × 7 = 77.
For, 16 : 112
=> 16 × 7 = 112.
Similarly, for 21 ∶ ?
=> 21 × 7 = 147.
Hence, the correct answer is "Option B".
