Answer 1

Correct Answer - Option 3 : × and -

Given equation: 25 - 5 × 50 ÷ 10 + 35 = 155

Let's check through options:

1. + and -

25 + 5 × 50 ÷ 10 - 35 = 155

25 + 5 × 5 - 35

25 + 25 - 35

50 - 35

15 ≠ 155

2. × and ÷ 

25 - 5 ÷ 50 × 10 + 35 = 155

25 - 1/10 × 10 + 35

25 - 1 + 35

60 - 1

59 ≠ 155

3. × and -

25 × 5 - 50 ÷ 10 + 35 = 155

25 × 5 - 5 + 35

125 - 5 + 35

160 - 5

155 = 155 

Hence, × and - is correct.
