Cow gives 2 Liters of Milk.

Buffalo gives 5 Liters of milk.

Goat gives 250 ml of milk.

The total milk required by a cattler is 40 Liters.

The cattler must keep 20 animals of all the three types.

Can you help the cattler decide what number of each animals must he keep to satisfy his needs?

Before you go for the answer please comment your answer below!

1 cow,7 buffaloes and 12 goats..and it is done yeahhhhhhhhhhhhhhh :)

ReplyDeletecow 1 x 2 = 2 liter

ReplyDeletebaffalo 5 x 7 = 35 liter

goat 250ml x 12 = 3 liter

total bacam 40 liter..of each sort of three animal!!

ReplyDeleteit is hard to under stand but try

ReplyDeletegiven 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))

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

ReplyDelete12 goats*250= 3ltr.

ReplyDelete7 buffaloes*5= 35ltr.

1 cow*2= 2ltr.

ttl -20 animals, 40ltrs.

yeppii :) :)
