Question

519 is related to 781 following a certain logic. Following the same logic, 642 is related to 904. To which of the following is 485 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 3is not allowed.)

• A. 721
• B. 794
• C. 756
• D. 747

Answer 1

Answer:

D. 747

We compare the pattern:

Given:

519 → 781

Check operation on whole numbers:

$519 + 262 = 781$

So rule = add 262

Verify with second pair:

642 → 904

642 + 262 = 904

Pattern confirmed

Now apply to 485:

485 + 262 = 747

Final Answer:

747
