Maths Work ========================================================= If , object sold at 15% loss ---

100% is the total cost price. then sell price ratio will be 75:100

More simply.. by making it a fraction - 75/100 and cutting it down - 3/4 the ratio will be 3:4 - sell price ratio(S.P).

cost price = 4:4 ------------------------------------------------------------------------------------------------------ -> Experimenting with numbers To understand all these ... much clearly.. then lets take the example of $100.

Suppose, the cost price is $100. Given, the loss is $15, we can determine the cost price as $75. Because,

Clue: S.P = Sell price C.P= Cost price

In this way, the ratio can be determined as:

S.P= 75:100 or 3/4 C.P= 100:100 or 4/4

Tip: Always understand math problems by experimenting with given percentages. =========================================================
