To find the selling price of the toy car that Robi sold at a loss of 10%, you can use the formula for selling price after a loss.
If the cost price is \( x \), then the selling price after a loss of 10% can be calculated as follows:
\[
\text{Selling Price} = \text{Cost Price} - \text{Loss}
\]
The loss is 10% of the cost price, which is:
\[
\text{Loss} = 0.10 \times x = 0.1x
\]
Thus, the selling price can be calculated as:
\[
\text{Selling Price} = x - 0.1x = 0.9x
\]
Therefore, the expression for the selling price is \( 0.9x \).
The correct answer is \( \boxed{0.9x} \).
If the cost price is \( x \), then the selling price after a loss of 10% can be calculated as follows:
\[
\text{Selling Price} = \text{Cost Price} - \text{Loss}
\]
The loss is 10% of the cost price, which is:
\[
\text{Loss} = 0.10 \times x = 0.1x
\]
Thus, the selling price can be calculated as:
\[
\text{Selling Price} = x - 0.1x = 0.9x
\]
Therefore, the expression for the selling price is \( 0.9x \).
The correct answer is \( \boxed{0.9x} \).
