What will come in place of the question mark (?) in the following equation if ‘+’ means ‘÷’, ‘−’ means ‘×’, ‘×’ means ‘+’ and ‘÷’ means ‘−’?
(280 + 10 × 20) − 8 ÷ 6 = ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 378.
Given equation: (280 + 10 × 20) − 8 ÷ 6 = ?
+’ means ‘÷’, ‘−’ means ‘×’, ‘×’ means ‘+’ and ‘÷’ means ‘−’, then
(280 ÷ 10 + 20) × 8 − 6 = ?
= (28 + 20) × 8 − 6
= 48 × 8 − 6
= 384 - 6 = 378
