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?
Select the correct option
A) 8%  B) 9%  C) 10%  D) 11%  E) None
Solution   Actual price	= Rs. (25 + 2.50)   = Rs. 27.50   Therefore, saving	= (2.50 / 27.50 ×100)%   = 100 / 11%   = 9×1/11%   = 9%.   Answer 9%
