Question 11

Sahil sold an item for ₹ 280 at a loss of 20%. The cost price of the item was:

Solution

Let assume CP to be Rs x

Then, loss in rupess =$$\frac{20}{100}\times x$$ = $$\frac{x}{5}$$

Since SP = CP - Loss

SP = Rs x - $$\frac{x}{5}$$

=$$\frac{4x}{5}$$

given that sp = 280 

so,

280 = $$\frac{4x}{5}$$

so x = 350

so cp = Rs 350
