Question<\/strong> : The coach of a cricket team buys 3 bats and 6 balls for Rs 3900. Later, she buys another bat and 2 more balls of the same kind for Rs 1300. Represent this situation algebraically and geometrically.<\/p>\n\n\n\n

Solution<\/strong> : Let us denote the set of one bat by Rs x and one ball by Rs y. Then, the algebraic representation is given by the following equations :<\/p>\n\n\n\n

3x + 6y = 3900 …….(1)<\/p>\n\n\n\n

and x + 2y = 1300 …..(2)<\/p>\n\n\n\n

To obtain the equivalent geometric representation, we find two points on the line representing each equation. That is, we find two solutions of each equation.<\/p>\n\n\n\n

These solutions are given below in the table.<\/p>\n\n\n\n

For 3x + 6y = 3900<\/p>\n\n\n\n

x<\/td>0<\/td>1300<\/td><\/tr>
y<\/td>650<\/td>0<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

For x + 2y = 1300<\/p>\n\n\n\n

x<\/td>500<\/td>100<\/td><\/tr>
y<\/td>400<\/td>600<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

We plot the points A(0, 650) and B(1300, 0) to obtain the geometric representation of 3x + 6y = 3900 and C(500, 400) and D(100, 600) to obtain the geometric representations of x + 2y = 1300.<\/p>\n\n\n\n

We observe that these lines are coincident.<\/strong><\/p>\n\n\n\n
