Answer» Correct Answer - Option 1 : 8 - 3÷ 16× 36 + 6 = 14
1) 8 - 3÷ 16× 36 + 6 = 14 After changing the symbol by their meaning, we get: L.H.S = 8 × 3- 16+ 36 ÷ 6 = 24 – 16 + 6 = 30 – 16 = 14 = R.H.S 2) 8 + 3÷ 16× 36 - 6 = 14 After changing the symbol by their meaning, we get: L.H.S = 8 ÷ 3- 16+ 36 × 6 = 2.67 – 16 + 216 = 218.27 – 16 = 202.27 ≠ R.H.S 3) 8÷ 3 - 16 + 36× 6 = 14 After changing the symbol by their meaning, we get: L.H.S = 8- 3 × 16 ÷ 36+ 6 = 8 – 1.34 + 6 = 14 – 1.34 = 12.66 ≠ R.H.S 4) 8× 3÷ 16 + 36 - 6 = 14 After changing the symbol by their meaning, we get: L.H.S = 8+ 3- 16 ÷ 36 × 6 = 8 + 3 – 2.64 = 11 – 2.64 = 8.36 ≠ R.H.S Hence, ‘8 - 3÷ 16× 36 + 6 = 14’ is the correct answer. |
