Question

an article is sold at the loss of 20% there is a yield of rupees 60 more if the article is sold at the profit of 20% find the cost price of the article ​

Answer 1

Answer:

let CP of article is x rs and SP of article y rs

loss=(x-y)/x ×100=20

we get 4x=5y

if we want to get profit of 20% ,we need to increase SP by 60 rs

so SP= y+60 rs

profit =( y+60-x)/x ×100=20

we get 5y+300=6x

we have 5y=4x ,put it in above equation

4x+300=6x

2x=300

x=150 rs
