If ‘-‘ means ‘division’, ‘ +’ means ‘multiplication’, ‘×’ means ‘addition’, and ‘÷’ means ‘subtraction’, which of the following equations is correct?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 10 - 2 + 3 ÷ 9 × 2 = 8.
‘-‘ → ‘division’,
‘ +’ → ‘multiplication’,
‘×’ → ‘addition’,
‘÷’ → ‘subtraction’
Option 1: 20 9 9 - 4 + 6 = 33
20 - 9 + 9 ÷ 4 × 6 = 33
20 - 9 + 13.5 = 33
24.5 = 33
Option 2: 20 + 6 - 4 × 9 6 = 32
20 × 6 ÷ 4 + 9 - 6 = 32
30 + 3 = 32
33 = 32
Option 3: 10 + 3 - 2 × 9 ÷ 2 = 21
10 × 3 ÷ 2 + 9 - 2 = 21
15 + 7 = 21
22 = 21
Option 4: 10 - 2 + 3 ÷ 9 × 2 = 8
10 ÷ 2 × 3 - 9 + 2 = 8
15 - 7 = 8
8 = 8
Hence, the correct answer is 10 - 2 + 3 ÷ 9 × 2 = 8.
