Let the cost of 1 litre milk be Re. 1
Milk in 1 litre mix. in 1st can = |
3 |
litre, C.P. of 1 litre mix. in 1st can Re. |

Milk in 1 litre mix. in 2nd can = |
1 |
litre, C.P. of 1 litre mix. in 2nd can Re. |

Milk in 1 litre of final mix. = |
5 |
litre, Mean price = Re. |

By the rule of alligation, we have:
C.P. of 1 litre mixture in 1st can C.P. of 1 litre mixture in 2nd can |
|
Mean Price

∴ Ratio of two mixtures = |
1 |
: |

= 1 : 1. |

So, quantity of mixture taken from each can = |
