In what ratio must a shopkeeper mix peas and soyabean of ₹16 and ₹25 per kg respectively, so as to obtain a mixture of ₹19 per kg?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 2 : 1
By the rule of alligation, the cheaper and dearer items are mixed in the ratio of the distances of their prices from the mean price, taken crosswise: (dearer price − mean) : (mean − cheaper price).
Peas: \(25-19=6\)
Soyabean: \(19-16=3\)
Peas : soyabean \(=6:3=2:1\)
