Aptitude - Profit and Loss - Discussion

I think option B is correct.

Gain = Selling Price(SP) - Cost Price(CP)

Gain% = (Gain/C.P)*100

Simple logic.

If the c.p of 20 articles is = 20rupees,
So 20=100%.

The s.p of x articles is = 20rupees,
if gain% is 25% it means 20 rupees of c.p is = 125%.
We need to understand that 5 is 25% of 20.

So 100%+25%=20+5,
125%=25.

Now we can find the s.p of 1 articles
s.p 25÷20 c.p =1.25.

The s.p of 1 articles is =1.25.
Now we can find the sold (x) articles those make 20 rupees
20÷1.25=16.

Sold articles is =16 Ans,
And.
20*1.25=25,
25 = 125% of c.p 20.

Hi, guys this is the best tricks to solve this question lets start.
Old scooter price =4700
Spend on repair =800
The Total cost of scooter is=5500.
He sells the scooter on rupees 5800.
Now gain = s.p-c.p
5800-5500=300..
Gain=300.
Gain%=gain * 100\c.p
Gain%=300*100\5500=5.454.

Total cost= 4800+700=5500,
and selling price= 5800,
So profit= 300,
And profit% = 300/5500*100 = 5(5/11).

@Manoj.

We need not convert simply into 5.4545.
Just after coming 60/11, 11*5+5=60, 60 divide 11= 5 approx remaining is 5.
So, 5 5/11 that mean 11*5 + 5= 60 same as 60/11.

CP = 4700 + 800 = 5500.
SP = 5800,
Gain% = 300 * 100/5500 = 60/11 = 5-5/11.

I didn't understand how 5 upon 5/11 is the correct answer?
My answer is 5 upon 25/55.
Please explain it.

Here it is Given;

CP of 20 articles = SP of x article.
So let us consider 1aricle is Rs 1 In CP.
So CP = 20.
And at all, we have profit percent of 25%.
So we can equate like;
20 = (1+25% of 1)* X,
20 = 1.25X,
X = 20/1.25,
X = 16.

TOTAL CP = 4700 + 800 = 5500.
SELLING PRICE = 5800.
PROFIT = 5800 - 5500 = 300,
= P/CP * 100.
= 300/5500 * 100,
= 5 5/11%.
