Aptitude - Profit and Loss - Discussion

Thanks Satish. Its really simple.

Raj answer is so simple:).

Thanks @balaji

Balaji answer is nice thanks to you.

Consider C.p=x, S.P=2x, Profit=3x
gain=S.p-C.P=2x-x=x
so gain=x,
profit=(gain/C.P*100)=(x/x*100)
profit=100%....

simple man....

I don't think there should be necessary for explanation for this sum. It is just the common sense we need to apply. Coming to the Question.

If selling price is doubled, the profit triples. Find the profit percent.

I think we can answer this question without considering the 3 times of profit. I mean to read the question like this -- (If selling price is doubled, Find the profit percent.)

It is obviously 100%, right?

Hi, even if the selling price is doubled, we have to consider the cost price also to find the profit. What you mentioned was correct but not all the problems.

See if the sp is 100 and if it is doubled then sp =200, bot the cost price may be 50.. so the profit is 150 not 100.. so here the profit is 150%. so we have to consider the terms 'the profit triples.

Say sp = x
profit = y
then
x-cp=y(general eqn sp-cp=gain)
2x-cp=3y(condition given in the problem)

solving these two we get

y=cp

so the profit is 100%

Saleem is rite here.
assume s.p 10
c.p 5
s.p doubles 10+10 20
c.p triples 5+5 10+10 20.
100%

@Guneet your right dude good explanation.

Assume c.p=100rs

then the s.p.=200rs(double price according to the question)

profit=300rs (triple profit of c.p.)

gain=s.p.-c.p.

gain=200-100

gain=100

now we put the value in formula..

gain%=gain/c.p.*100

=100/100*100

gain =100% it's very easy, i think now u have no doubt regarding this.....have a nice day.......
