Question

Since the price of pillow is decreased by 25%, one can purchase 4 pillows more for rs. 60. what is the original price of pillow

Answer 1

Let us assume that the price of the pillow was x

If the price is reduced by 25%, then the price will be:

100% - 25% = 75%

75/100 × x = 0.75x

Therefore, 75x can get you 4 more pillows

That means :

60/0.75x = (60/x) + 4

Multiply the above equation by 0.75x, you will get:

60 = 45 + 3x

3x= 60 - 45

3x = 15

x= 5

Therefore the original price of the pillow was Rs. 5

Answer 2

Answer:

Let us assume that the price of the pillow was x

If the price is reduced by 25%, then the price will be:

100% - 25% = 75%

75/100 × x = 0.75x

Therefore, 75x can get you 4 more pillows

That means :

60/0.75x = (60/x) + 4

Multiply the above equation by 0.75x, you will get:

60 = 45 + 3x

3x= 60 - 45

3x = 15

x= 5

Therefore the original price of the pillow was Rs. 5
