Hey there! Thanks for the question!
Q. A rice is 20 Rs/kg and another is 25 Rs/kg. Both should be mixed in what ratio to sell it for Rs. 21.50 Rs/kg.
A. To get the answer for this question, we need to use rule of alligation.
Price of first item = 20 Rs
Price of second item = 25 Rs
Mean price = 21.5 Rs
20 25

21.5

25 - 21.5 = 3.5 21.5 - 20 = 1.5
Ratio = 3.5/ 1.5 = 35/15 = 7/3 = 7 : 3
Therefore, both the items should be mixed in the ratio 7 : 3 to obtain a selling price of 21.50 Rs/kg.
Would appreciate if you mark me as brainliest.
Thanks and have a great day! :))
