Question

By selling 300 articles a man lost the selling price of 25 articles find the find his loss percentage had he purchased them for 390 what would have been the SP of an article ​

Answer 1

Answer:

Let each article SP = Re 1

for 300 articles, SP = Rs 300

Loss = Rs 25

CP = Rs 325

so, loss% = (25×100)/325 = 7.69 % loss

now, CP = Rs 390 for 300 articles

when CP is Rs 325 then for one article SP = Re 1

when CP is Re 1 then SP for one article = Rs 1/325

when CP is Rs 390 then SP for one article = Rs (1/325)×390 = Rs 1.20

Answer 2

Given,

By selling $300$ articles a man lost the selling price of $25$ articles.

Let each article price $= 1$ rupee

$300$ articles $=$ Rs. $300$

A man lost the selling price of $25$ articles

So,

Cost price $=300+25$

Cost price $=325$

Loss% $=\frac{cost price-selling price}{cost price}\times 100$

Loss% $=\frac{325-300}{325}\times100$

Loss% $=7.69$%

Now,

Cost price $=$ Rs. $390$ for $300$ articles

When cost price $325$ then for one article selling price is Rs. $1$

So,

Cost price $=\frac{1}{325}$

When cost price $390$ then selling price of one article $=\frac{390}{325}=1.2$

Therefore, the selling price of an article is Rs. $1.2$.
