Let cost of one ball be Rs. y

x+2y=300..(i) Blue line

2x+3y=525..(ii) Red line

The graphs for the equation are shown in the attached plot.

From graph, solution is x=150,y=75

Hence, cost of one bat is Rs. 150 and cost of one ball is Rs. 75

Cost of one bat and one ball is Rs. 150+Rs. 75=Rs. 225
