C) 48%

original price = 100
price, after 25% decrease = 75
price, after 10% during the sale = 75-10% of 75 = 67.5
the amount of price to be increased = 100-67.5 = 32.5
approx % to be increased to get the original price = 32.5/67.5 = 48%.

100 --> 75 --> 67.5 back to 100 so new % will be : 100-67.5/67.5 * 100 = 48%

i thinks so. the question seems from Kapalan. Kaplan question are pretty vauge.

That answer would be correct if the question was asked to find the following price: The original price of an article was reduced by 25 percent. During a special sale the new price was decreased by 10 percent. By approximately what percent of the original price would the price now have to be increased in order to restore the price of the article to its original amount?

It has to be
A) 32.5%

% Increase = (Amount Increased) / (original amount) * 100

To restore the original price
% Increase = (32.5)/100 *100 = 32.5%

Is it 48 or 32.5? I thought it was 48 but PR says 32.5

original price = 100
price, after 25% decrease = 75
price, after 10% during the sale = 75-10% of 75 = 67.5
the amount of price to be increased = 100-67.5 = 32.5
approx % to be increased to get the original price = 32.5/67.5 = 48%.

I think this last line approx % to be increased to get the original price = 32.5/67.5 = 48% is not required since the question is what percent would the price now have to be increased in order to restore the price of the article to its original amount which is 100.

We have taken the original price as 100 so we don't need to go further....the answer 32.5 is already a percent value.

My tutor said 48. Every problem with a percent change, you just take the increase of the final price
