Question

a men sale and article at a profit of 25% if he he had bought it at 20% less and sold it for Rs10.5 ₹
less he would have gained 30% find the rate of cost price find the cost price of an article ​

Answer 1

Let's suppose cost price(CP1) of the article be Rs 100

Then selling price(SP1) would be Rs 125

New cost price @20% less = Rs 80

New selling price @30% profit = 130% of 80 = Rs 104

Now, difference between the 2 selling prices = 125–104 = Rs 21.

When difference is 21 then CP = Rs 100

When difference is 1050 then CP = 100*1050/21 = Rs 5000

Hence the cost price of the article is Rs 5000
