If ‘+’ means ‘−’, ‘−’ means ‘×’, ‘×’ means ‘÷’ and ‘÷’ means ‘+’, what will come in place of ‘?’ in the following equation?
137 ÷ 80 × 5 - 4 + 34 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 167.
Given conditions: ‘+’ means ‘−’, ‘−’ means ‘×’, ‘×’ means ‘÷’ and ‘÷’ means ‘+’
Given equation: 137 ÷ 80 × 5 - 4 + 34 = ?
After interchanging the expression becomes:
= 137 + 80 ÷ 5 × 4 - 34
= 137 + 16 × 4 - 34
= 137 + 64 - 34
= 201 - 34 = 167
