Question

4 chairs and 3 tables cost is 210 rupees and cost of 5 chairs and 2tables is 75 rupees find the cost each chair and table separately

Answer 1

let the cost of 1 chair= x

cost of 1 table=y

2 eqn we get are,

4x+3y=210    -i

5x+2y=75      -ii

multiplying eqn i by 2 and eqn ii by 3

8x+6y= 420

15x+6y=225

subtracting them,

-7x=-195

x= 27.85-cost of 1 chair

substitute value of x in eqn i,

value of y= 32.1- cost of 1 table
