Answer 1

Answer:

Here is your answer:-

∴ The C.P. of 10 articles =1×10=Rs.10

∴ S.P. of 9 articles= C.P. of 10 articles

∴ S.P. of 9 articles=Rs.10

Hence, we calculate the cost of 9 articles,

C.P. of 9 articles=1×9

=Rs.9

∴Profit=S.P.−C.P.

Profit=10−9

Profit=Rs.1

∴Profit%= Profit/C.P ×100

Profit%=1/9 ×100

Profit%=11.11%.
