Question

if 9 articles are sold at the cost price of 10 articles what is profit percent​

Answer 1

Answer:11.11%

Step-by-step explanation:let one article's cost price be 100 then 10 article's cost price will be 1000

We know,

10 article's c.p.=9 article's s.p.

So,

9 article's s.p.=1000

1 article's s.p.=1000/9 =111.11

So 100 is changed to 111.11

So profit%=11.11%
