Question

15. If cost price = Rs 125, profit = Rs 20, then profit % = ___________.

Answer 1

Answer:

Let CP =x=x, so S.P =1.2x

When CP is Rs. 100 less,

CP=x−100

SP=1.2x−100

Now,

1.2x−100=1.24×(x−100)

On solving , we get

x=600

CP=Rs.600

➤ Given :-

Cost price :- ₹ 125

Profit :- ₹ 20

➤ To Find :-

Profit percentage of the given sum............

➤ Formula required :-

$\large \tt \dashrightarrow \orange{ \boxed{ \tt \gray{ \dfrac{Profit}{Cost \: Price} \times 100}}}$

➤ Solution :-

Profit percentage :-

$\tt \longrightarrow \dfrac{20}{125} \times 100$

$\tt \longrightarrow \dfrac{20 \times 100}{125} = \dfrac{200}{125}$

$\tt \longrightarrow \cancel \dfrac{200}{125} = \boxed{ \tt 1.6 \bf \small\%}$

$\Huge\therefore$The profit percentage of the given sum is 1.6 $\bf\%$.
