If ‘+’ means ‘−’, ‘−’ means ‘×’, ‘×’ means ‘÷’ and ‘÷’ means ‘+’, what will come in place of ‘?’ in the following equation?
83 ÷ 12 - 65 × 13 + 47 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 96.
Given conditions: ‘+’ means ‘−’, ‘−’ means ‘×’, ‘×’ means ‘÷’ and ‘÷’ means ‘+’
Given equation: 83 ÷ 12 - 65 × 13 + 47 = ?
After interchanging the expression becomes:
= 83 + 12 × 65 ÷ 13 - 47
= 83 + 12 × 5 - 47
= 83 + 60 - 47
= 143 - 47 = 96
