Here’s what’s going on:

- First, combine the numbers on the left side:

- 137.40 + 230.41 = 367.81

- 367.81 - 110.35 = 257.46

- Now, look at the right side:

- 157.38 + 4.23×? = 257.46

- Move 157.38 to the other side to isolate the unknown:

- 257.46 - 157.38 = 100.08

- So, you get 4.23×? = 100.08

- ? = 100.08 ÷ 4.23 ˜ 23.67

- Now compare:

- Option 1: 22 (close, but a little low)

- Option 2: 25 (a tad high, but closest)

- Option 3: 20 (too low)

- Option 4: 35 (way off)

- Option 5: 28 (a little high)

Here’s the thing: 23.67 is closest to 25. So,

Correct Answer: Option 2, 25
