Answer 2

The ratio of three types of sugar to be mixed so that mixture may cost Rs 40 per kg = 1:2:7

• This types of problem is solved using allegation method.

• Ratio between Rs 32 sugar and Rs 42 sugar = (42-40) / (40-32)

                                                                             = 1:4

• Ratio between Rs 37 sugar and Rs 42 sugar = (42-40) / (40-37)

                                                                             = 2:3

• Overall ratio bet Rs 32, Rs 37 and Rs 42 sugar to make Rs 40 sugar

                 = 1:2:7
