A shopkeeper sells a pair of sunglasses at a profit of 25%. If he had bought it at 25% less and sold it for Rs.10 less then he would have gained 40%. The cost price of the pair of sunglasses is:

ANSWER  

Let the cost price be p

So selling price will be Rs 125/100 p = Rs 5 p/4

Now selling price = Rs 5 p /4 – 10

5 p/4 – 10 = 140 /100 x 3 p/4

                = 21 p / 20

5 p/4 – 21 p/20 = 10

4 p / 20 = 10

 4 p = 200

  P = 50

So the cost price of pair of sunglasses will be Rs 50

Answer 2

Answer:

50

Step-by-step explanation:

Let the cost price be р

So selling price will be Rs 125/100 p = Rs 5 p/4

Now selling price = Rs 5 p /4 – 10

5 p/4 – 10 = 140 /100 x 3 p/4

= 21 p /20

5 p/4 - 21 p/20 = 10

4 p/ 20 = 10

4 p = 200

P = 50

So the cost price of pair of sunglasses will be Rs 50
