Answer 1

Step-by-step explanation:

let,

price of bat =x

price of ball=y

3x+6y=3900.....(1)

x+3y=1300.......(2)

after solve the equation (1) and (2),

we get, x=1300, y=0

Answer 2

$\huge{\boxed{\huge{\red\star\mathfrak\purple{\large{\underline{\underline{Answer!}}}}}}}$

Let the price of a bat be x and ball be रु y

Given that 3 bats and 6 balls are bought for रु 3900

$\therefore$

3x+6y= 3900

⟹x+2y= 1300

Also given that one bat and 3 balls of the same kind cost रु 1300

$\therefore$

x+3y= 1300
