Correct Answer: 800 Kg


Solution : Total amount of rice = 1200 kg
Total profit = 7%
Let the amount of rice he sold at 5% profit be $a$
Then, the amount of rice he sold at 11% profit will be $(1200-a)$
According to the question,
$a(1+\frac{5}{100})+(1200-a)(1+\frac{11}{100})=1200(1+\frac{7}{100})$
⇒ $1.05a+1.11(1200-a)=1200\times 1.07$
⇒ $0.06a=1200\times 0.04$
⇒ $a=800$
Hence, the correct answer is 800 Kg.
