Question

after selling 72 article a men looses selling price of 9 article find loss percentage?????​

Answer 1

Answer:

Step-by-step explanation:

C.P of 16 = S.P of 14

\frac{C.P}{S.P}=\frac{14}{16}=\frac{7}{8}

C.P = 7    ,       S.P = 8   ,   Profit = 1

Gain%  =   (\frac{Gain\times 100}{C.P})

=\frac{1}{7}\times 100=14\tfrac{2}{7}%

Let the S.P of one article = RS 1

S.P of 72 articles = 72 × 1 = 72

Loss = 9

C.P = 72 + 9 = 81

Loss% =  \frac{Loss\times 100}{C.P}

=  \frac{9}{81}\times 100=11\tfrac{1}{9}%

C.P of one article = RS.1

C.P of 144 articles = RS.144

Profit = 9

Profit % = \frac{Profit\times 100}{C.P}

=\frac{9}{144}\times 100=6\tfrac{2}{3}%
