Mr Roy gives rupees 679.90 to his maid.The maid spends 0.2 part of this amount in buying groceries and the remaining  amount is her salary. How much does the maid earn

To determine how much the maid earns, we first need to calculate how much she spends on groceries, and then subtract that from the total amount given by Mr. Roy.

### Step 1: Calculate the amount spent on groceries
The maid spends 0.2 (or 20%) of the total amount on groceries. So, we calculate 0.2 of 679.90:

\[
\text{Amount spent on groceries} = 0.2 \times 679.90 = 135.98
\]

### Step 2: Calculate the remaining amount (her salary)
The remaining part is the maid's salary. Subtract the amount spent on groceries from the total amount:

\[
\text{Maid's salary} = 679.90 - 135.98 = 543.92
\]

Thus, the maid earns **₹543.92** as her salary.
