Question

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

Answer 1

Answer:

let bat = x and ball=y

Step-by-step explanation:

3x +6y=3900

x+3y=1300

Answer 2

Answer:

Reffer imagr.

let rate of bat = xRs.

 and rate of ball = yRs.

3x+6y=3900.(i)

 and x+3y=1300.(ii)

or x=(1300−3y) 

now equation (i) can be written as

 3(1300−3y)+6y=3900

 3900−9y+6y=3900

 ∴y=0 

Ans:- x=1300
