In what ratio wheat at ₹38 per kg should be mixed with wheat at ₹26 per kg so that on selling the mixture at ₹39 per kg, there would be a profit of 30%?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e 1 : 2.
Selling price = 39 and Profit = 30%
⇒ Cost price of mixture = 39 ÷ 1.3 = 30
Use alligation between ₹38 and ₹26 to get mean ₹30: = 38 – 30 = 8
⇒ 30 – 26 = 4
Ratio = 4 : 8 = 1 : 2
Final Answer: The ratio is 1 : 2
