Correct Answer - Option 1 : +, ÷, -, ×, =
1) +, ÷, -, ×, =
Given expression: 14 * 24 * 3 * 5 * 3 * 7
After replacing the *’s by the signs given on the option above, we get:
14 + 24 ÷ 3 - 5 × 3 = 7
=> 14 + 8 – 15 = 7
=> 22 – 15 = 7
=> 7 = 7
2) +, ÷, ×, -, =
Given expression: 14 * 24 * 3 * 5 * 3 * 7
After replacing the *’s by the signs given on the option above, we get:
14 + 24 ÷ 3 × 5 - 3 = 7
=> 14 + 8 × 5 – 3 = 7
=> 14 + 40 – 3 = 7
=> 54 – 3 = 7
=> 51 ≠ 7
3) ÷, +, ×, -, =
Given expression: 14 * 24 * 3 * 5 * 3 * 7
After replacing the *’s by the signs given on the option above, we get:
14 ÷ 24 + 3 × 5 - 3 = 7
=> 0.58 + 15 – 3 = 7
=> 15.58 – 3 = 7
=> 12.58 ≠ 7
4) +, ×, ÷, -, =
Given expression: 14 * 24 * 3 * 5 * 3 * 7
After replacing the *’s by the signs given on the option above, we get:
14 + 24 × 3 ÷ 5 - 3 = 7
=> 14 + 14.4 – 3 = 7
=> 28.4 – 3 = 7
=> 25.5 ≠ 7
Hence, ‘+, ÷, -, ×, =’ is the correct answer.
