let CP of a ball x.
loss= CP - SP.
5x= 17x - 720,
x=60.
loss= CP - SP.
5x= 17x - 720,
x=60.

Let cp for 1 ball = x rs.
sp for 1 ball =720/17 rs.
***please note***(for 17 balls, loss = 5x therefore loss behind 1 ball = 5x/17)
Now, loss over 1 ball = c.p. over 1 ball - sp over 1 ball.
5x/17 = x - 720/17,
x = 60.
sp for 1 ball =720/17 rs.
***please note***(for 17 balls, loss = 5x therefore loss behind 1 ball = 5x/17)
Now, loss over 1 ball = c.p. over 1 ball - sp over 1 ball.
5x/17 = x - 720/17,
x = 60.

17(cp-720) = 5cp,
cp = 60.
cp = 60.

Let,
Each Ball cost of price x.
We know,
Cost price - selling price = loss.
17x- 720= 5x,
Or, 17x - 5x= 720,
Or, 12x= 720,
Or, x=720 ÷ 12.
0r, x=60,
So, x=tk 60 cost of each ball.
Each Ball cost of price x.
We know,
Cost price - selling price = loss.
17x- 720= 5x,
Or, 17x - 5x= 720,
Or, 12x= 720,
Or, x=720 ÷ 12.
0r, x=60,
So, x=tk 60 cost of each ball.
