SP of 17 balls will be subtracted CP of 5 balls. Because there is a loss equal to 5 balls in selling of 17 balls.

Consider cp of 1 ball =x
for 17 balls=17x;
loss=cp-sp(here 17balls cost price-17balls selling price)
i.e 17x-720;
for 5 balls cp is 5x;
in the question he give 17 balls loss=cp of 5 balls
i.e 17x-720=5x;
17x-5x=720;
12x=720;
x=720/12;
x=60.

Why it cann't be solved like this:
Loss = CP-SP
Acc to the ques
SP is given for 17 balls i.e 720
So SP of 1 ball = 720/12
let cp of 1 ball = x
loss = 5x (loss equals to the cp of 5 balls)
5x=x-720/17
5x = 17x-720/17
5x-17x= 720/17
12x = 720/17
x=???

5x/17=x-720/17(loss for 17 balls)
5x/17 = (17x-720)/17
5x=17x-720
12x = 720
x=720/12
x=60

Anil.. one doubt for me.
i clear about this problem., but in your explanation u said that SP is given for 17 balls = 720
So SP of 1 ball = 720/12
How it came?
SP of 1 ball = 720/17 na?

Let cost price of 1 ball=x
then cost price of 17 balls=17x
loss is equal to 5 balls cost price(given in problem)=5x
selling price=c.p-loss=17x-5x=12x
but original selling price=720
.
. . 12x=720
x=60
c.p of 1 ball=60
C.P. of 12 balls = S.P. of 17 balls = Rs.720.
