Question

Arun purchased 30 kg of wheat at the rate of Rs 11.50 per kg and 20 kg of wheat at the rate of Rs 14.25 per kg . He mixed the two and sold the mixture. Approximately what price per kg should he sell the mixture to make 30% profit?

• A. Rs 14.80
• B. Rs 15.40
• C. Rs 15.60
• D. Rs 16.40

Answer 1

The correct option is D Rs 16.40

C.P. of $50Kg$ wheat = $(30\times 11.50+20\times 14.25)$

$=Rs.(345+285)=Rs.630.$

S.P of $50Kg$ wheat=130% of 630=$\frac{130}{100}\times 630=819Rs$

S.P. per kg=$\frac{819}{30+20}$

=$\frac{819}{50}$

=$16.40Rs.$
