Aptitude - Profit and Loss - Discussion

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.

Please give the formula to find Gain and Gain%.

I don't understand the how you get the 5(5/11).

I doesn't understand logic behind it please help me.

How did 5.5/11 come?

Gain% = (300 x 100)/5500

= 30000/5500

= 300/55

= 60/11

= 5.45454545....

= 5(5/11) [ after converting 5.4545.. into vulgar fraction]

Note: What is a vulgar fraction?

A fraction in the form of one integer divided by another, non-zero, integer.

A vulgar fraction is one where the numerator (the number on the top) is bigger than the denominator (the number on the bottom). More pedantically, the absolute value of the numerator is bigger than the absolute value of the denominator.

I hope you understand. Have a nice day!
