A man buys lemons at 3 for Rs. 5 and an equal number at 2 for Rs. 4. He mixes them and sells at 5 for Rs. 9. Find his gain or lo
melamori03 [73]

3 lemons cost = Rs. 5

Each lemon cost = Rs. 5/3

2 lemons Cost = Rs. 4

Each lemon cost =

= \frac{4}{2}  =  \frac{2}{1}  = 2

Total Cost price of Each lemon =

\frac{5}{3}  +   \frac{2}{1}

LCM = 3

\frac{5}{3}  +  \frac{2 \times 3}{1 \times 3}  =  \frac{6}{3}  =  \frac{5 + 6}{3}  =  \frac{11}{3}

Each lemon Cost =

=  \frac{11}{3}  \div  \frac{2}{1}

=  \frac{11}{3}  \times  \frac{1}{2}

=  \frac{11}{6}

Selling price of 5 lemons = 9

Selling price of 1 lemon = 9/5

loss\% =  \frac{loss \times 100}{CP}

=  \frac{ \frac{4}{6} -  \frac{9}{5}  \times 100 }{ \frac{11}{6} }

=    \frac{\frac{55 - 54}{30} \times 100}{ \frac{11}{6} }

=   \frac{\frac{1}{30}  \times 100}{ \frac{11}{6} }

=  \frac{100}{30}  \times  \frac{6}{11}

=  \frac{20}{1}  = 1 \frac{9}{11} \% \: loss
