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

Answer 1

Correct Answer - Option 3 : -, ×, +, ÷

Given equation,

12 * 3 * 6 * 8 * 4 = − 4

Put options in place of '*'

1) 12 × 3 − 6 + 8 ÷ 4 ≠ − 4

2) 12 ÷ 3 × 6 + 8 − 4 ≠ − 4

3) 12 − 3 × 6 + 8 ÷ 4 = − 4

4) 12 + 3 ÷ 6 × 8 − 4 ≠ − 4

Hence, the correct answer is −, ×, +, ÷.
