Question

If 'CONSTABLE' is coded as 91, what will be the code number for 'STABLE'?

• A. 97
• B. 59
• C. 79
• D. 75

Hint:

Give each letter its alphabet position and add them up, the same way CONSTABLE was coded.

Answer 1

The Correct Option is B

A quicker route uses subtraction instead of adding six letters fresh. Notice that STABLE is CONSTABLE with the letters C, O and N removed.

1. Find the value removed: C = 3, O = 15, N = 14, so together they contribute $3 + 15 + 14 = 32$ to the code of CONSTABLE.
2. Subtract from the known total: CONSTABLE codes to 91, so removing C, O, N leaves $91 - 32 = 59$ for the remaining letters S, T, A, B, L, E, which spell STABLE.
3. Cross-check: this 59 matches the direct letter-by-letter sum done the first way, confirming the answer is consistent regardless of method.

So the code for STABLE is 59, matching option B. \[ \boxed{59} \]
