Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 56.
Given equation: 117 - 13 ÷ 6 + 24 × 26
Given conditions: '+' means '-', '-' means '÷', '÷' means '×', and '×' means '+'
After interchanging the expression becomes:
= 117 ÷ 13 × 6 - 24 + 26
= 9 × 6 - 24 + 26
= 54 - 24 + 26
= 56
