Answer 1

Answer:

25

Step-by-step explanation:

Let the number of milch animals = x.

One-fifth are cows = x/5

Thrice the square root of group are buffaloes = 3√x

Number of goats = 5

Now,

Total number of animals = (x/5) + 3√x + 5

⇒ x = (x/5) + 3√x + 5

⇒ x * 5 = x + 15√x + 25

⇒ 5x - x = 15√x + 25

⇒ 4x = 15√x + 25

⇒ 4x - 25 = 15√x

On Squaring both sides, we get

⇒ (4x - 25)² = 225 * x

⇒ 16x² - 200x + 625 = 225x

⇒ 16x² - 425x + 625 = 0

⇒ 16x² - 25x - 400x + 625 = 0

⇒ x(16x - 25) - 25(16x - 25) = 0

⇒ (x - 25)(16x - 25) = 0

⇒ x = 25, x = 25/16[∵ Cannot be in fraction]

⇒ x = 25

Therefore,

Number of milch animals = 25
