Question
Pulses of two varieties, which are costing for Rs.26/kg
and Rs.78/kg as they mixed together. when the price of the mixture obtained is Rs.54/kg then what will be the ratio of the two varieties which are mixed?ÂSolution
By using alligation we can conclude the solution as -Â 
hence the required ratio will be - 24 : 28Â = 6:7Â
