Answer:
Ram bought that motorcycle for Rs. 36000
Step-by-step explanation:
Given that:
Amount gained = 25%
Selling price of motorcycle = Rs. 45000
As 100% will be the original price, then 25% will be added into it.
125% will be the new percentage.
Let,
x be the original price of motorcycle.
125% of x = 45000
![\frac{125}{100}x=45000](https://tex.z-dn.net/?f=%5Cfrac%7B125%7D%7B100%7Dx%3D45000)
1.25x=45000
Dividing both sides by 1.25
![\frac{1.25x}{1.25}=\frac{45000}{1.25}\\](https://tex.z-dn.net/?f=%5Cfrac%7B1.25x%7D%7B1.25%7D%3D%5Cfrac%7B45000%7D%7B1.25%7D%5C%5C)
x=36000
Hence,
Ram bought that motorcycle for Rs. 36000
