Question

if the selling price is doubled the profit triples find the profit%

Answer 1

heyyy dear ☺☺......



let the CP be x and SP be y

So,the profit=y-x(sp-cp)

Now,

when sp is doubled

New Sp=2y and new profit=2y-x

When Sp is doubled and profit triples

New profit = 3 * Old profit

or,2y-x =3(y-x)

or,2y-x =3y-3x

or,-x + 3x =3y - 2y

or,2x = y

or,y =2x

so , profit =y - x

=2x - x (y =2x)

=x

NOW,

PRofit % =profit / Cp * 100

=x/x * 100



hope it's help uuu

=100%

Answer 2

$\huge\underline\mathrm{SOLUTION:-}$

$\pink{\bf{Given}\begin{cases}\sf{ \red{Selling\:price\:is\:doubled,}\: }\\\sf{ \green{the\:profit\:triples.}\: }\end{cases}}$

$\pink{\bf{To\:Find}\begin{cases}\sf{ \red{The\:profit\:percent = \:?} \: }\end{cases}}$

$\huge\underline\mathrm{ExPlanation:-}$

Let the C.P be Rs.100

And S.P be Rs.x

Then:

• The profit is (x-100)

Now he S.P is doubled,

• Then the new S.P is 2x

New profit is (2x-100)

Now as per the given condition;

➠ 3(x-100) = 2x - 100

By solving, we get

• x = 200

Then:

The Profit percent = (200-100)/100

The Profit percent = 100

Hence:

• $\dag$The profit percentage is 100%.
