Question
Two varieties of rice are mixed together – type 'P'
costing Rs. 60/kg and type 'Q' costing Rs. 100/kg. The mixture is then sold for Rs. 126/kg, yielding a 40% profit. Find the ratio in which rice of type 'Q' is added to type 'P'.Solution
ATQ,
Cost price of mixture = (126 / 1.4) = Rs. 90 Let 'm' kg and 'n' kg of rice of type 'P' and 'Q' respectively be mixed. So, (60m + 100n) ÷ (m + n) = 90 Or, 60m + 100n = 90m + 90n Or, 10n = 30m Or, n : m = 3 : 1
