Correct Answer: 19


Solution : Given:
+ and – and × and ÷
55 + 42 × 7 ÷ 11 – 30 = ?

After interchanging the signs, the new equation is –
= 55 – 42 ÷ 7 × 11 + 30
= 55 – 6 × 11 + 30
= 55 – 66 + 30
= 85 – 66
= 19

Therefore, the required answer for the equation is 19. Hence, the fourth option is correct.
