Question

A trader mixes $26kg$ of rice at $Rs.20$ per kg with $30kg$ of rice of other variety at $Rs.36$ per kg and sells the mixture at $Rs.30$ per kg. His profit percent is:

• A. No profit, no loss
• B. $5$%
• C. $8$%
• D. $10$%
• E. None of these

Answer 1

The correct option is B $5$%

C.P. of $56kg$ rice $=Rs.(26\times 20+30\times 36)=Rs.(520+1080)=Rs.1600$.
S.P. of $56kg$ rice $=Rs.(56\times 30)=Rs.1680$.
$\therefore Gain=(\frac{80}{1600}\times 100)$% $=5$%.
