  6. it is hard to under stand but try
    given required animals is 20, and milk is 40 liters
    that means on avg for 1 animal should give 2 liters of milk
    our condition is amount of milk=2*no.of animals
    keep no. of cows aside because 1 cow gives 2 liter of milk it satisfy the condition
    let no.of buffalo=x
    no.of goats =z
    from our condition
    5x+z/4=2(x+z)
    on solving
    12x=7z
    x/z=7/12
    hence it cannot simplify, x=7,z=12 x+y=19
    there for tot no.of buffalos and goats=19,remaining one animal is cow.
    hence the question is solved.
    this question has two answers
    1)7 buffaloes,12 goats and 1cow
    2)0 buffaloes,0 goats and 20 cows
    main condition is (tot amount of milk=2(tot no of animals))

  7. 1st answer is the best because he mentioned that cattler must keep all the three types

  8. 12 goats*250= 3ltr.
    7 buffaloes*5= 35ltr.
    1 cow*2= 2ltr.

    ttl -20 animals, 40ltrs.

  10. just 20 cows
    they are milder than buffalos, and more efficient than goats
    rancher's point of view
