11 is related to 55 following a certain logic. Following the same logic, 12 is related to 60. To which of the following is 15 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)

Correct option is B

We are given the number pairs:
11 → 55
12 → 60
15 → ?
Let's identify the pattern.
Finding the Relationship
Checking the difference between the given numbers:
11→55
12→60
Observing a possible formula: Result=(Number×5)
Verifying:
(11×5)=55
(12×5)=60
Applying the Pattern to 15
(15×5) = 75
 Finding the Correct Answer
The correct answer is 75, which matches Option B.
