Question

Select the correct combination of mathematical signs that can sequentially replace the * signs from left to right to balance the following equation.

24 * 6 * 32 * 4 * 2 * 28

1. ×, -, ÷, +, =
2. ÷, -, ×, +, =
3. +, ÷, ×, -, =
4. ÷, +, -, ×, =

Answer 1

Correct Answer - Option 4 : ÷, +, -, ×, =

1) ×, -, ÷, +, =

Given expression: 24 * 6 * 32 * 4 * 2 * 28

After replacing the ‘*’ by the symbols given, we get:

24 × 6 - 32 ÷ 4 + 2 = 28

=> 144 – 8 + 2 = 28

=> 146 – 8 = 28

=> 138 ≠ 28

2) ÷, -, ×, +, =

Given expression: 24 * 6 * 32 * 4 * 2 * 28

After replacing the ‘*’ by the symbols given, we get:

24 ÷ 6 - 32 × 4 + 2 = 28

=> 4 – 128 + 2 = 28

=> 6 – 128 = 28

=> -122 ≠ 28

3) +, ÷, ×, -, =

Given expression: 24 * 6 * 32 * 4 * 2 * 28

After replacing the ‘*’ by the symbols given, we get:

24 + 6 ÷ 32 × 4 - 2 = 28

=> 24 + 0.75 – 2 = 28

=> 24.75 – 2 = 28

=> 22.75 ≠ 28

4) ÷, +, -, ×, =

Given expression: 24 * 6 * 32 * 4 * 2 * 28

After replacing the ‘*’ by the symbols given, we get:

24 ÷ 6 + 32 - 4 × 2 = 28

=> 4 + 32 – 8 = 28

=> 36 – 8 = 28

=> 28 = 28

Hence, '÷, +, -, ×, =' is the correct answer.
