Find the profit percente​

Answer 1

★Given:-

• The selling price of 10 rulers is the same as the cost price of 15 rulers

★To Find:-

• Profit %

★Solution:-

• Let the cp of 1 ruler be Rs.1
• Then, Cp of 15 rulers = Rs. 15

We Have,

• C.p Of 15 rulers = C. p Of 10 rulers

$\therefore \: S. p \: Of \: 10 \: Rulers \: = Rs.10$

• So, Gain = S.P - C. P
• = 15 - 10 = Rs. 5

$\therefore \: Gain\% \: = \frac{Gain}{C. p} \times 100 \\ \frac{5}{1 \cancel0} \times 10 \cancel0 \\ Gain\% \: = 50\%$

Hence, Profit % is 50%.
