Question

Nandini bought a cap for Rs 90 and sold it for Rs 100. What is her profit percentage?

Answer 1

Step-by-step explanation:

Cost price of pen=Rs. 90

Selling price of pen=Rs. 100

Since, SP>CP.

Hence,

Gain=SP−CP=100−90=Rs. 10

So,

Gain = SP - CP = 100 - 90 = Rs.10

Gain (%)

$= \frac{gain}{cp} \: \times 100 = \frac{10}{90 } \times 100 = 11 \times \frac{1}{9}$

Answer 2

Question :-

→ Nandini bought a cap for Rs 90 and sold it for Rs 100. What is her profit percentage?

Given :-

→ Cost Price of cap = Rs. 90

→ Selling Price of cap = Rs. 100

To Find :-

→ Profit percentage

Solution :-

→ As we know that ,

$\sf Profit \% = \dfrac{SP-CP}{CP} \times 100\%$

→ Let's solve !!

$\sf Profit \% = \dfrac{100-90}{90} \times 100\% \\\\\\\rightarrow \dfrac{10}{90} \times 100\% \\\\\\= 11\dfrac{1}{9} \%$

∴ The profit % is $\sf 11\dfrac{1}{9} \%$
