Answer 1

An article was sold for Rs. 2770. Had it been sold for Rs.3000 there would have beenan additional gain of 10%. Cost price of the article is Rs.2300

Answer 2

Solution :-

Let the cost price be Rs. x

Original Selling Price = Rs. 2770

Original Profit = (2770 - x) Rs. 

Profit % = (2770 - x)*100/CP

Now, new Selling Price = Rs. 3000

Original CP = Rs. x

New profit = (3000 - x) Rs. 

New profit % = (3000 - x)*100/CP

(3000 - x)*100/CP - (2770 - x)*100/CP = 10

(300000 - 100x)/CP - (277000 + 100x)/CP = 10

23000/CP = 10

10CP = 23000

CP = 23000/10

CP = 2300

So, the original Cost price is Rs. 2300
