Question 131

The owner of an electronics shop charges his customers 22% more than the cost price .If the customer paid Rs 10,980 for DVD player then the what was the cost price of that DVD?

Solution

Let cost price = $$Rs. 100x$$

Selling price = Rs. 10,980

=> Profit % = $$\frac{10980 - 100x}{100x} \times 100 = 22$$

=> $$10980-100x=22x$$

=> $$22x+100x=122x=10980$$

=> $$x=\frac{10980}{122} = 90$$

$$\therefore$$ Cost price = $$100 \times 90 = Rs. 9000$$

=> Ans - (E)
