The cost of Type 1 rice is Rs. 15 per kg and Type 2 rice is Rs. 20 per kg. If both Type 1 and Type 2 are mixed in the ratio of 2 : 3, then the price per kg of the mixed variety of rice is:
Answer: Option
Explanation:
Let the price of the mixed variety be Rs. x per kg.
By rule of alligation, we have:
| Cost of 1 kg of Type 1 rice Cost of 1 kg of Type 2 rice | ||
| Rs. 15 | Mean Price Rs. x | Rs. 20 |
| (20 - x) | (x - 15) | |
 |
(20 - x) | = | 2 |
| (x - 15) | 3 |
60 - 3x = 2x - 30
5x = 90
x = 18.

Assume it to be 2 kg and 3kg.
2x15 = 30 and 20x3 = 60.
30+60 = 90.
90/2+3 = 18.
