Explanation:

- Start with 0.2 ÷ 0.025:

- 0.2 divided by 0.025 is 8.

- Add 39 to the result:

- 8 + 39 = 47.

- Calculate 0.92 ÷ 0.2:

- 0.92 divided by 0.2 is 4.6.

- Multiply by 5:

- 4.6 × 5 = 23.

- Add this to the previous result:

- 47 + 23 = 70.

- Now, calculate 4.9 ÷ 0.07:

- 4.9 divided by 0.07 is 70.

- Subtract this result:

- 70 - 70 = 0.

- Solution:

- The correct answer is option 2, which is 0.
