Aptitude - Profit and Loss - Discussion

Explanation:

@Yasir maybe it would help:

First of all, we need to find gain%, not the gain amount. So there is no need of count of toys as far we have SP and CP of one toy. Let's go with the example below:

Let's assume CP of 1 toy = 200.
And SP of 1 toy= 250.
So, gain% = (250- 200)/200*100= 25 %.
If we raise the no of toys i.e 2,3,5. So on,
Now, CP of 2 toys= 200*2= 400,
And SP of 2 toys= 250*2= 500,
Gain%. = (500-400)/400*100= 25%.
So, basically, %age would remain the same for any number of item sold and it is the gain or loss amount that changes.

Answer is B. No need to find a number of toys. Without this, we can calculate profit %.

Lets say for 1 toy sp=250. Cp=225 profit % =25/225*100=11.111.

Lets say for 5 toys sp=250*5=1250, cp=5*225. Profit=125. Profit% =125/1125*100=11.11.

So it does not matter to consider a number of toys as profit percent is independent of it.

Agree?

CP of 60 hats = 60*25 = 1500
20% gain on this means ,he should get 1800

He sold 20 at 35rs = 700
He sold another 20 at 30 = 600
Total he has is 1300rs

He should get [1800-1300]500rs more to reach 1800 and make 20% profit
hence he has to sell the left 20 hats to get 500

500/20 = 25rs each

In this question, they have mentioned S.P of some toys is Rs.250 they did not mention as S.P of one toy is Rs.250. Even if we have a cost price of one toy we can't find the profit per cent since we don't know the selling price of one toy. So, I think option C is correct.

In problem it is mention as "A shopkeeper sells some toys at Rs. 250 each.".

Considering the word "each" which means he is selling n no. of toys @ Rs.250 per toy.

So there is no need of total no. of toys to calculate profit %.

A dealer bought 60 hats at Rs. 25 each. He sold 20 hats at Rs. 35 each and another 20 at Rs. 30 each. At what rate should he sell the remaining hats to make a profit of 20% in the total outlay? Show all the process.

In this question, as it is not mentioned that each toy will have the same CP, the CP of each toy may be different.

Hence only the CP of each toy is necessary to calculate the Selling price.

@Himanshu you are correct in this one!

The option is "Cost price of each toy".

How do we suppose to take the number of toys in this case if its not mentioned in the question?

The selling price of each toy is given. So the Cost price of each toy is what we need to find.

Profit% formula is [ (Profit of each toy)/(Cost price of each toy)] × 100.

Here cost price of each toy is mentioned. So I think if we want to calculate total C.P. Then no.of toy is also require. Please suggest me.
