Correct Answer: 1 : 4


Solution :
Given:
Type 1 sugar price = Rs. 12 per kg
Type 2 sugar price = Rs. 7 per kg
The price after mixing both types of sugar = Rs. 8 per kg
Using the rule of alligation, we get,
the ratio of Rs. 12 per kg to Rs. 7 per kg = (8 – 7) : (12 – 8) = 1 : 4
Hence, the correct answer is 1 : 4.
