If ‘+’ = ‘÷’, ‘×’ = ‘+’, ‘–’ = ‘×’, ‘÷’ = ‘–’ . Then, which one of the following four equation would be correct ?
Answer & explanation
Correct answer: option 3
Option (a)
15 ÷ 5 × 2 - 6 + 3
15 - 5 + 2 × 6 ÷ 3
15 - 7 × 2
15 - 14
1 ≠ 30
Option (b)
15 × 5 + 2 - 6 ÷ 3
15 + 5 ÷ 2 × 6 - 3
15 + \(\frac{5}{2}\) × 6 - 3
15 + 15 - 3
27 ≠ 60
Option (c)
15 + 5 - 2 ÷ 6 × 6
15 ÷ 5 × 2 - 6 + 6
3 × 2 - 6 + 6
6 - 6 + 6
6 = 6
Option (d)
15 - 5+ 2 × 6 ÷ 3
15 × 5 ÷ 2 + 6 - 3
15 × \(\frac{5}{2}\) + 6 - 3
15 × 2.5 + 6 - 3
37.5 + 6 - 3
34.5 ≠ 39
So, correct answer is option (C).
