Correct Answer - Option 2 : 14 and 18, + and ×
1) 14 and 18, + and –
Given expression: 16 × 18 + 2 - 14 ÷ 3 = 38
After replacing the numbers and symbols, we get:
16 × 14 – 2 + 18 ÷ 3 = 38
=> 224 – 2 + 6 = 38
=> 230 – 2 = 38
=> 228 ≠ 38
2) 14 and 18, + and ×
Given expression: 16 × 18 + 2 - 14 ÷ 3 = 38
After replacing the numbers and symbols, we get:
16 + 14 × 2 - 18 ÷ 3 = 38
=> 16 + 28 – 6 = 38
=> 44 – 6 = 38
=> 38 = 38
3) 16 and 3, - and ÷
Given expression: 16 × 18 + 2 - 14 ÷ 3 = 38
After replacing the numbers and symbols, we get:
3 × 18 + 2 ÷ 14 - 16 = 38
=> 54 + 0.14 – 16 = 38
=> 54.15 – 16 = 38
=> 38.15 ≠ 38
4) 16 and 14, - and ×
Given expression: 16 × 18 + 2 - 14 ÷ 3 = 38
After replacing the numbers and symbols, we get:
14 - 18 + 2 × 16 ÷ 3 = 38
=> 14 – 18 + 10.67 = 38
=> 24.67 – 18 = 38
=> 6.67 ≠ 38
Hence, ‘14 and 18, + and ×’ is the correct answer.
