If in a certain code, 917 = 56 and 826 = 36, then in that code 735 =

Correct option is B

Information Given:
917 = 56, 826 = 36, 735 = ?

Formula Used:
Result = (First digit - Second digit) × Third digit

Explanation:
Logic: Subtract second digit from first digit, then multiply by third digit.
Step-by-step: For 917: $(9 - 1) \times 7 = 8 \times 7 = 56$.
For 826: $(8 - 2) \times 6 = 6 \times 6 = 36$.
For 735: $(7 - 3) \times 5 = 4 \times 5 = 20$.

Short Trick:
(d1 - d2) × d3 gives the coded value.

Final Answer:
20

Final Correct Option:
(B)

So the correct answer is (b)
