Step-by-step explanation:

Total cost of 3 chairs and 2 tables=4500

Total cost of 2 chairs and 3 tables =5500

4500+5500=10000

Answer is:- 10000/=

Answer 2

let cost of chair be x
let cost of table be y

acc to ques

3x+2y=4500
mark as eq 1

2x +3y =5500
mark as eq 2

substitute eq 1 and 2

6x +4y=9000
6x+9y=16500

then by subraction

-5y=-7500
y=1500

put y in eq 1
3x +3000=4500
3x=1500
x=500

hence
chair cost 500
table cost 1500

total cost of a chair and a table =2000
