Question
A purchased an article for Rs 2000. She sold the article
at 15% profit. She then added Rs 200 to the amount received and purchased a purse such that the seller of purse gained 25%. Find the cost price of purse for the seller.Solution
Amount received by A after selling the article = 1.15 × 2000 = Rs. 2300 Therefore, selling price of the purse for the seller = 2300 + 200 = Rs. 2500 Let the cost price of the purse for the seller be Rs. x According to the question, 1.25x = 2500 Or, x = 2500/1.25 = 2000 Therefore, cost price of the purse for the seller = Rs. 2000
The lines x + y = 9 and x - y = 3 intersect at point P. Find the coordinates of P.
Solve: 2x + 3y = 19 and x − y = 2, Find x and y
Solve for x: 5x − 7 = 3x + 9
