Question

एक भैस 1लीटर एक गाय 500 गा्म एक बकरी 250गा्म तो 20जानवर और 20लीटर दूध

Answer 1

Answer:

Let, X be the no of buffalos

Y be the no of cows

Z be the no of goats

Total animals are 20

X + Y + Z = 20 ----------(1)

So, the total milk by buffalo = 1000X

the total milk by cows = 500Y

the total milk by goat's = 250Z

1000X + 500Y + 250Z = 20000

DIVIDE ON BOTH SIDE BY 250

SO,

4X + 2Y + Z = 80 ---------(2)
