Question

solve this question A shopkeeper allows a cash discount of 12.5% on a machine a customer pays and amount of rs437.50 for a machine at what price is the machine listed ​

Answer 1

Answer:

500

Step-by-step explanation:

12.5% = 125/1000 = 1/8

8 ----------> 7

Here , the discounted price is

7 units = 437.50

1 unit = 437.50/7 = 43750/700

= 6250/100

= 62.5

So 8 units = 62.5 × 8 = 500

Answer 2

Let the listed price of machine be x, then  

x - 12.5% of x = 437.50

⇒ x - 12.5x/100 = 437.50

⇒ (100x - 12.5x)/100 = 437.50

⇒ 87.5x = 437.50 × 100

⇒ 87.5x = 43750

⇒ x = 43750/87.5 = 500

∴ The listed price of machine is Rs. 500
