Aptitude - Profit and Loss - Discussion

In this problem clearly mentioned the selling price is doubled & profit is tripled.

Let C.P = 1 than S.P = 2.

Profit = (S.P)-(C.P).

=2-1 = 1.

Profit% = 1*100 = 100%.

Let cost price = x and selling price = y.

Then, in question they saying that the selling price is double a and profit triple that means.

First condition here our selling price is y then according to question will be 2y.

Second condition and again they are saying that our profit is triple and our profit is x-y i.e. cp-sp = profit.

Then according to question here our profit = 3(y-x).

Then according to first condition we will get:

Profit = (2y-x) ----- (1).

And according to second condition will get:

Profit = 3(y-x) ----- (2).

By using equation (1) and equation (2) we will get:

(2y-x) = 3(y-x).

Or 3(y-x) = (2y-x).

After solving this equation we will get 100% profit.

Thanks friends and good luck. And according to second condition we will get.

They have said that if SP is doubled Profit becomes 3 times.

Let CP = X, & SP = Y.

As per the condition 2Y = 3(Y-X) ----------- (1).

Therefore, SP-CP = Profit.

2Y-CP = 3(Y-X).

CP = 3X-Y.

Put this in formula.

[2Y-3(Y-X)/3X-Y]*100.

3X-Y.
----- *100.
3X-Y.

= 100%.

You should calculate % profit after the price is doubled and the profit tripled.

Very simple and easy approach.

Let SP =10.

And profit be X. So CP = 10-X equation 1.

Now SP doubles means it became 20. And profit triples means it become 3X.

So now CP = 20-3X equation 2.

Now equate equation 1 and 2.

10-X = 20-3X.

X = 5 means it is profit.

Now with X we can calculation CP by any one equation.

Then profit percent = P*100/CP.

5/5*100 = 100%.

It is the easiest way to solve.

Its very simple.

C.P = x.

S.P = 2y.

Profit =3x.

3x.

(2y-x).

But 2y = S.P = C.P + Profit = x + 3x.

Now + we will solve + 3x.

------- * 100.

x+3x-x.

Left hand portion will cut all and remain 100.

Ya its hard but not that much only use + logic + hope + so you will get this.

Here we suppose.

CP = x.

Then SP = 2x (According to the Question. ).

Then Profit = SP - CP.

Profit = 2x-x.
Profit = x.

And Profit% = x*100/x.
Profit% = 100% Answer.

Suppose the cost is 10 and the selling price is 15 then the profit is 5 after all the selling price being double means 30 the profit being triple means 5+5+5=15. So our selling price is 15 or our profit is also 15 then the profit is 100 percent.

Why here 2y-x is done? As we are only doubling selling price which is y.

If you do not understand any method or formulas, solution it helps you.

Let initially there are 20 articles with 5 each ones price.

20*5=100.

Increase double S. P of each article.

20*10=200.

Profit % = (200-100/100) *100 = 100%.
