19 is related to 287 following a certain logic. Following the same logic, 23 is related to 347. To which of the following is 28 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 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 Answer :
422
Solution :
The correct option is 422.
To find the relation, let us analyze the mathematical pattern between the numbers in the given pairs.
Step 1: Analyze the first relationship (19 is related to 287)
Let us test the logic of multiplying the first number by 15 and then adding 2:
This calculation matches the given relation.
Step 2: Verify the logic with the second relationship (23 is related to 347)
Applying the exact same rule to 23:
Since the logic holds true for both pairs, the pattern is confirmed to be:
Step 3: Apply the verified logic to 28
Using the same rule for the number 28:
Therefore, 28 is related to 422 under the same logic.
