Profit and Loss

11.

On selling 17 balls at Rs. 720, there is a loss equal to the cost price of 5 balls. The cost price of a ball is:

Rs. 45

Rs. 50

Rs. 55

Rs. 60

Answer: Option

Explanation:

(C.P. of 17 balls) - (S.P. of 17 balls) = (C.P. of 5 balls)

C.P. of 12 balls = S.P. of 17 balls = Rs.720.

C.P. of 1 ball = Rs.		720		= Rs. 60.
		12

cp of 17 balls = 720 + cp of 5 balls,
cp of 17 balls - cp of 5 balls = 720,
cp of 12 balls = 720,
cp of 1 ball = 720/12,
So, cp of 1 ball = 60.

Let,
Cost price of 1 ball is x.
so, cost price of 5 balls = 5x,
and cost price of 17 balls = 17x.

In case of selling goods at loss,
Selling price+loss= Cost price.
=> 720+5x = 17x.
=> 12x = 720.
=> x = 60.

Ans: Cost price of each ball is 60.

From the given info by adding 5 balls cp to the 17 balls sp which is 720, we will get cp of 17 balls.

Let X be cp of one ball.
= 720+5x = 17x,
12x = 720,
X = 60.

@Kiran.

It is 720/17 not 720/12 for the S. P of 1 ball.
