Question

the total cost of 3 tables and 2 chairs is 575. if a chair cost rs 25 less than that of a table. find the cost of a table and a chair.

Answer 1

let cost of table be x

let cost of chair be y

x=y+25......................i

3x+2y=575.......................ii

substitute i in ii

3(y+25)+2y=575

3y+75+2y=575

y=500/5

y=100................iii

substitute iii in i

x=125

∴cost of one table= Rs125

cost of one chair=Rs100
