Correct Answer: 2 and 24


Solution : Given:
I. 18 ÷ 3 + 6 × 2 – 8
II. 15 × 3 – 45 ÷ 5 + 30

After interchanging + and – the equation becomes –
I. 18 ÷ 3 – 6 × 2 + 8
 = 6 – 6 × 2 + 8
 = 6 – 12 + 8
 = 2
II. 15 × 3 + 45 ÷ 5 – 30
= 15 × 3 + 9 – 30
= 45 + 9 – 30
= 24

So, the equations are equal to 2 and 24. Hence, the fourth option is correct.
