Question

A shopkeeper sold a laptop at a gain of 20%. Had it been sold for 1000 more, the gain would have been 25%. Find the CP of the laptop.​

Answer 1

Step-by-step explanation:

Let say cost Price of the Laptop 100C

Rs

Gain of 20% = (20/100)100C =

Selling Price = 100C + 20C = 120C Rs

if Sold at RS 1000 More than Selling Price = 120C Rs

Gain = 120C + 1000 - => Gain = 20C + 1000

Gain = 25 %

=> 100C = 20C + 1000

=> 25C 20C + 1000

=> 5C = 1000

=> 200

Cost Price of Laptop = 100C = 100 * 200 = Rs 20000
