Question

If '-' means division, '×' means addition, '÷' means multiplication and '+' means subtraction, then which of the following equations is correct?
1. 18 + 6 × 8 - 16 ÷ 4 = 62
2. 18 × 6 ÷ 8 + 16 - 4 = 62
3. 18 + 6 × 8 ÷ 16 - 4 = 62
4. 18 - 6 ÷ 8 × 16 + 4 = 62

Answer 1

Correct Answer - Option 2 : 18 × 6 ÷ 8 + 16 - 4 = 62

Check with options one by one:

Option 1: 18 + 6 × 8 - 16 ÷ 4 = 62

18 - 6 + 8 ÷ 16 × 4 

18 - 6 + 2 

14 ≠ 62

L.H.S ≠ R.H.S

Option 2: 18 × 6 ÷ 8 + 16 - 4 = 62

18 + 6 × 8 - 16 ÷ 4

18 + 48 - 4

62 = 62

L.H.S = R.H.S

Option 3: 18 + 6 × 8 ÷ 16 - 4 = 62

18 - 6 + 8 × 16 ÷ 4

18 - 6 + 32

44 ≠ 62

L.H.S ≠ R.H.S

Option 3: 18 - 6 ÷ 8 × 16 + 4 = 62

18 ÷ 6 × 8 + 16 - 4

24 + 16 - 4

36 ≠ 62

L.H.S ≠ R.H.S

Hence, option (2) is correct.
