Question
In what ratio coffee at 315 Rs/kg should be mixed with
the coffee at 355 Rs/kg so that after mixture its rate become 330 Rs/kg if the quantity of 1st type is 30 kg what will be the quantity of the 2nd coffee?Solution
Ratio = 25:15 = 5:3 1st type coffee is 30 kg. So, 5 means 30 kg. Therefore, 2nd type coffee = 30 x (3/5) = 18 kg
