Question

. If the ratio of CP and SP of an article is 5:4, then the loss per cent is:​

Answer 1

Answer:

Since the ratio is 5 : 4, if the cost price is 100, the selling price will be 100×4/5 = 80.

Therefore the loss is 20 percent, as profit or loss is calculated on the cost price.

     

Answer 2

CP:SP = 5:4 (which means the loss is 1 unit)

so, 5 × X% = 1

5 × X/100 = 1

X/20 = 1

X = 20% (Thus the loss is 20%)
