Aptitude - Profit and Loss - Discussion

Here the cost price we have got 60 and its selling price is also 60. So how loss is possible?

17 balls selling we get 720.
Good.but loss is there, we don't know. It was given that out of 5 balls equals to loss c.p. i.e subtract 17 from 5 = 12, I want c.p of each ball so, 720/12 = 60.

Nice explanation @Tarun.

I didn't understand this, kindly give simple examples.

Hi, can anyone help me by solving this problem?

If the cost price of 10 chairs is equal to the selling price of 16 chairs, then the loss percent is?

a) 37.5%
b) 20%
c) 9.6%
d) 17.5%

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.

Nice explanations. Thank you all.

Thank you all for explaining the solution.

Thank you for explaining it properly @Manasa.

Guys!
Check the question, how much did they sell 17 balls for?? Rs.720? Correct.

So now you know how much 17 balls cost, which is 720 bucks.
17=720.

Now,
when you sell 17 balls for 720 rupees, but the question clearly says you face a loss of '5 balls profit'.

How come? So how much does a ball exactly cost?

Lets do one thing,

Selling 17 for 720 but the loss of 5, we will minus the 5 with the 17, so,

17-5 = 12.
12 is our profit for 720. which is, 720=12!!

So,
Cost of 1 ball *12=720
Cost of 1 ball = 720/12
Cost of 1 ball = 60.
