Thecostof1chairisy

∴costof2chairsare2y

accordingtothequestion

totalcostof3tablesand2chairsare1850

∴3x+2y=1850→(i)

x=75+y→(ii)

sinceinquestionitisgiven

thatcostoftableis75morethanchairs

(i)and(ii)

3x+2y=1850→(i)

x−y=75→(ii)

multiplyingequation(2)by(2)

weget

2x−2y=150→(iii)

add(i)and(iii)

weget

5x=2000

∴x=4000thereforecostofonetableisRs.400

Substitutingthevalueofxin(ii)weget

400−y=75

∴y=400−75=325
