What will come in place of the question mark (?) in the following equation if ‘+’ means ‘×’, ‘×’ means ‘−’, ‘−’ means ‘÷’ and ‘÷’ means ‘+’?
18 ÷ 4 + 3 × 2 − 2 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 29.
Given equation: 18 ÷ 4 + 3 × 2 − 2 = ?
If ‘+’ means ‘×’, ‘×’ means ‘−’, ‘−’ means ‘÷’ and ‘÷’ means ‘+’, then
18 + 4 × 3 − 2 ÷ 2 = ?
= 18 + 4 × 3 − 1
= 18 + 12 − 1
= 30 − 1
= 29
