Question

A housewife saved Rs \[250\] in buying a dress on sale. If she spent Rs \[25\] for the dress, she saved about?

Answer 1

Hint: At first, we will find the actual price of the dress. Then with the help of the actual price of the dress we will find the percentage of saving made by the housewife with respect to the given price.

Complete step-by-step answer:
It is given that she saved Rs \[250\] in buying a dress on sale. Then also it is given that she spent Rs. \[25\] for the dress.
We have to find the percentage that she saved about.
If she spent Rs. \[25\]for the dress,
Then the actual price of the dress is found by the addition of the price she bought with the amount she saved.
That is the actual price of the dress is Rs \[250 + 25 = \]Rs. \[275\]
Hence the actual price of the dress is Rs. \[275\].
Now we have to find the saved percentage of the housewife.
The formula for finding the saved percentage is \[\dfrac{{{\text{amount saved}}}}{{{\text{cost price}}}} \times 100\% \]
therefore, the saved percentage is \[\dfrac{{250}}{{275}} \times 100\% \]
Let us simplify the above equation we get,
The saved percentage of the price is \[90\% \].
Hence, the percentage of the amount saved by the housewife in buying the new dress is \[90\% \].

Note: When the selling price is more than cost price, then there will be gain. Suppose if the selling price is less than the cost price then there will be loss. But we are not finding the loss or gain in this problem. If we find the actual price of the dress correctly then we can easily solve the problem.
