My mother has prepared two types of sherbat. There is `5 kg` in `100 litre `sherbat of sugar the first type and `8 kg` sugar in `100 litre` sherbat of the second type. By mixing, these two types, I will prepare `150 litre` sherbat which contains `9 kg ` sugar. Forming simultaneous equation let us calculate how much quantity of two types sherbat will be mixed to prepare `150 litre` sherbat.
