Question

By selling 60 article a vendor makes a profit equal to the selling price of 15 articles find his gain percent

Answer 1

cp of 60 a = sp of 15a cp of 60a = 15x now cp of 60a is 15x sp of 60a is 60x since sp>cp therefore profit profit=sp-cp= 60x-15×=45x profit%=profit/cp×100 =45/15×100=300

Answer 2

His gain percent is 60%.

Step-by-step explanation:

Since we have given that

Number of articles he sold = 60

He get a profit equal to the selling price of 15 articles.

So, it becomes,

$40SP=40CP+15SP\\\\40SP-15SP=40CP\\\\25SP=40CP\\\\\dfrac{SP}{CP}=\dfrac{40}{25}=\dfrac{8}{5}$

So, ratio of SP to CP would be 8:11.

So, SP be 8x

CP be 5x.

So, Profit would be

SP - CP = 8x-5x=3x

So, Profit percentage would be

$\dfrac{3x}{5x}\times 100\\\\=3\times 20\\\\=60\%$

Hence, his gain percent is 60%.
