Question

four tables in three chairs together cost Rs 2250 and 3 tables and 4 chairs cost Rs 1950 find the cost of two chairs in one table

Answer 1

let the cost of table be x and chairs y

4x+3y=2250 Rs
3x+4y=1950 Rs


Compare Them

4x+3y=2250
3x+4y=1950
{Subtract them }

x-y=300
x=y+300

Take any Solution

4x+3y=2250
4(y+300)+3y=2250
4y+1200+3y=2250
7y=2250-1200
7y= 1050
y= 1050/7=150

x=y+300Rs
x=150+300=450 Rs

Two chairs =2y=2×150=Rs300
One Table =x =450
