    This problem can be easily solved by the Mixture and Alligation rule
    Cheap Costlier
    7.1 9.2
    8
    9.2 - 8 : 8 - 7.1 => According to the rule of allegation.
    = 1.2 : 0.9
    = 12:9
    = 4:3

    CP of two types of rice are 7.1 and 9.2 Rs/kg
    we need to mix the mixture in such a way that its mixture will cost Rs 8/kg
    difference of price in case of mixture one is 8-7.1=0.9
    difference of price in case of mixture one is 9.2-8=1.2
    thus we need to mix it in the ratio 1.2:0.9 or 12:9 or 4:3
    hence, we need the mixture in the ratio 4:3
