Question 118
Two chairs and three tables cost Rs 1025/- and 3 chairs and 2 tables cost is Rs 1,100/- .What is the difference between the cost one table and chair?
Solution
Let cost price of 1 chair = $$Rs.$$ $$x$$ and cost price of 1 table = $$Rs.$$ $$y$$
=> $$2x+3y=1025$$ -----------(i)
and $$3x+2y=1100$$ --------(ii)
Subtracting equation (i) from (ii)
=> $$(3x-2x)+(2y-3y)=(1100-1025)$$
=> $$x-y=75$$
$$\therefore$$ Difference between the cost one table and chair = Rs. 75
=> Ans - (A)
