Explanation:

To solve $137.40+230.41-110.35=157.38+4.23\times ?$:

- Begin by simplifying the left hand side:

$137.40+230.41-110.35=257.46$

- The equation becomes:

$257.46=157.38+4.23\times ?$

- Rearrange to solve for '?':

$257.46-157.38=4.23\times ?$

This equals: $100.08=4.23\times ?$

- Divide both sides by 4.23:

$?=\frac{100.08}{4.23}\approx 23.65$

- Check which option is closest to 23.65:

- Option 1, 22

- Option 2, 25

- Option 3, 20

- Option 4, 35

- Option 5, 28

- The closest approximation is Option 1, 22.
