A housewife saved Rs. 2.50 in buying an item on sale. If she spent Rs. 25 for the item, approximately how much percent she saved in the transaction ?
Answer & Solution
Correct Answer:
Option
B
Actual price :
$$= Rs. (25 + 2.5)$$
$$= Rs. 27.50$$
∴ Saving :
$$\eqalign{ & = \left( {\frac{{2.50}}{{27.50}} \times 100} \right)\% \cr & = \frac{{100}}{{11}}\% \cr & = 9\frac{1}{{11}}\% \approx 9\% \cr} $$
$$= Rs. (25 + 2.5)$$
$$= Rs. 27.50$$
∴ Saving :
$$\eqalign{ & = \left( {\frac{{2.50}}{{27.50}} \times 100} \right)\% \cr & = \frac{{100}}{{11}}\% \cr & = 9\frac{1}{{11}}\% \approx 9\% \cr} $$
