1. 3 × 8 ÷ 1 + 5 ÷ 7 × 2
2. 5 × 3 × 6 + 8 × 2 × 3
3. 8 ÷ 4 × 8 < 2 ÷ 1 × 3
4. 3 - 2 × 5 + 5 - 1 + 8

Answer 1

Correct Answer - Option 3 : 8 ÷ 4 × 8 < 2 ÷ 1 × 3

On substituting the actual signs in place of the given signs, we get:
3 × 8 ÷ 1 + 5 ÷ 7 × 2 → 3 + 8 - 1 = 5 - 7 + 2
⇒ 11 - 1 = 0 (False)
5 × 3 × 6 + 8 × 2 × 3 →  5 + 3 + 6 = 8 + 2 + 3
⇒ 14 = 13 (False)
8 ÷ 4 × 8 < 2 ÷ 1 × 3 →  8 - 4 + 8 > 2 - 1 + 3
⇒  16 - 4 > 1 + 3 (True)
3 - 2 × 5 + 5 - 1 + 8 →  3 ÷ 2 + 5 = 5 ÷ 1 = 8
⇒ 0.66 + 5 = 5 = 8 (False)

Hence, '8 ÷ 4 × 8 < 2 ÷ 1 × 3' is the correct option.
