In a sale, there is 25% off on all prices. A TV costs £90 in the sale. How much was it before the sale?

To work out how much something was before the discount, you have to divide the price (which is £90) by 75 (as this is the percentage that you paid). It's gives you £1.20. Therefore, 1% is £1.20. To find the original cost, which is 100%, you have to multiply it by 100. Multiplying £1.20 by 100 gives you £120. Therefore, the cost of the TV before the 25% reeducation was £120. Hope this helps :)

Since 25% off from sale: That means sale was = (100 -25)% = 75% of marked price.
Let marked price be = x. Therefore, 0.75x = 90. x = 90/0.75 Use your calculator. x = 120. Marked price before sale = £ 120.

The original price of the TV before the sale was £120. This was found by recognizing that £90 is 75% of the original price since there was a 25% discount. We can calculate the original price using the equation 0.75 x = 90 , which gives x = 120 .
