In what ratio wheat costing Rs. 17/ kg should be mixed with another wheat costing Rs. 12/kg to get a mixture costing Rs. 13.5/ kg?

In what ratio wheat costing Rs. 17/ kg should be mixed with another wheat costing Rs. 12/kg to get a mixture costing Rs. 13.5/ kg? Correct Answer 3 : 7

Applying Alligation formula,

(Quantity of higher Price/ Quantity of Lesser Price) = (Average Price – Lesser Price)/(Higher Price – Average Price)

⇒ (13.5 – 12)/(17 – 13.5) = 1.5/3.5 = 15/35 = 3/7

∴ Required Ratio = 3 : 7
