Question

2) A person wants to sell his chair and table. If he sells them at a total of Rs 525, he gets a
profit of 20% on table and 10% on chair. But if he sells them at a total of Rs 510, he gets a
profit of 10% on table and 20% on chair. Find the cost price of chair.​

Answer 1

Let the cost of chair be ₹x and cost of table be ₹y
120x+110y=52500
110x+120y=51000
Add and subtract
230x+230y=103500
X+y=450
And 10x-10y=1500
X-y=150
X=300 ,y=150
