A merchant wants to prepare a wheat blend priced at ₹28 per kilogram by mixing two different qualities of wheat. The first variety costs ₹20 per kilogram, while the second variety costs ₹32 per kilogram. In what weight ratio should these two varieties be combined so that the final mixture meets the desired cost?
Show answer & explanation
Correct answer: D
Explanation
Given:
Price of the first variety = ₹20/kg
Price of the second variety = ₹32/kg
Price of the mixture = ₹28/kg
According to the formula:
Ratio = (Higher Price − Mixture Price) : (Mixture Price − Lower Price)
Ratio = (32 − 28) : (28 − 20) = 4 : 8 = 1 : 2
