51 is related to 256 by certain logic. Following the same logic, 53 is related to 266. To which of the following is 55 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 / deleting / 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.)
276
✅ Answer: Option 1 — 276
Explanation:
We are given:
51 → 256
53 → 266
We need to find the number related to 55 using the same logic.
Step-by-Step Logic:
From 51 to 53, the input increases by 2, and the output increases from 256 to 266, i.e., by 10.
This means:
For every +1 in input, output increases by 5
Apply the same pattern to 55:
From 51 to 55 = +4
So, increase output by: 4 × 5 = 20
Starting from 256:
256 + 20 = 276
✅ Final Answer: 276
✅ Option 1 — 276 matches the pattern perfectly.
