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
(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
