Question

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

Answer 1

C.P. of $56$ kg rice = Rs.$(26\times 20+30\times 36)=$ Rs.$(520+1080)=$Rs.$1600$.

S.P. of $56$ kg rice $=$ Rs. $(56\times 30)=$ Rs.$1680$.

Gain $=(\frac{80}{1600}\times 100)\%=5\%$

$\therefore$ His profit is $5\%$
