Answer 2

Answer:  The correct option is (C) Rs. 5.66 per kg.

Step-by-step explanation:  Given that 4 kg of rice at rupees 5 per kg is mixed with 8 kg of rice at Rs 6 per kg.

We are to find the average price of the mixture.

We have

total price of 4 kg of rice and  8 kg of rice is

$T_p=4\times5+8\times6=20+48=Rs.~68,$

and total quantity of the rice is

$T_q=4+8=12~\textup{kg}.$

Therefore, the average price of the mixture is

$A_p=\dfrac{T_p}{T_q}=\dfrac{68}{12}=5.66.$

Thus, the average price of the mixture is Rs. 5.66 per kg.

Option (C) is CORRECT.
