Question:
The coach of a cricket team buys 3 bats and 6 balls for ` 3900. Later, she buys another bat and 3 more balls of the same kind for ` 1300. Represent this situation algebraically and geometrically.

Answer:

Let the cost of one bat and one ball be x Rupees and y Rupees respectively.

According to first condition,

3x + 6y = ₨ 3900 …………….(1)

According to second condition,

x + 3y = ₨ 1300 …………….(2)

Graphical Representation

From equation (1), 3x + 6y = 3900

Table value of x and y

x:	100	300	700
y:	600	500	300

From equation (2), x + 3y = 1300

Table value of x and y

x:	100	700	400
y:	400	200	300

1 Unit = 100
