The cost of type 1 rice is Rs. 20 per kg and type 2 rice is Rs. 30 per kg. If both Type 1 and Type 2 are mixed in the ratio 2 : 3, then the price per kg of the mixed variety is
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Rs.26
The price of the mixture is the weighted average of the two prices, with the quantities 2 and 3 as weights:
\( \displaystyle \text{Price per kg} = \frac{2 \times 20 + 3 \times 30}{2 + 3} \)
\( \displaystyle = \frac{40 + 90}{5} = \frac{130}{5} = 26 \)
So the mixture costs Rs.26 per kg.
