Question

One fourth of a herd of camels was seen in
forest. Twice of square root of the herd had
gone to mountains and remaining 15 camels
were seen on the bank of a river, find the total
number of camels.​

Answer 1

let the total no. of camel's be x

let the total no. of camel's be xnow, acccording to question

Herds seen in Forest=1/4 ×x=x/4

Herds seen on mountain=2√x

remaining camel's,which were seen on mountain=x-(2√x+x/4)

and this is equal to 15(given)

so,

15=x-(8√x+x)/4

15=(4x-x-8√x)/4

3x-8√x=60

sqaure both side we get

let √x=y

then x=y^2

so,

3y^2-8y-60=0

y={8+-(64+720)^1/2}/6

y=(8+28)/6

y=6

we know

Y=√x

6=√x

x=6^2

x=36

Hence total camel's will be 36

Answer 2

Answer:

Step-by-step explanation:

Solution :-

Let x be the total numbers of camels.

Camels seen in the forest = x/4

Camels gone to mountains = 2√x

According to the Question,

 x + 8√x + 60 = 4x

⇒ 3x - 8√x - 60 = 0 ....(i)

Putting √x = y in Eq (i), we get

⇒ 3y² - 8y - 60 = 0

⇒ 3y² - 18y + 10y - 60 = 0

⇒ 3y(y - 6) + 10(y - 6) = 0

⇒ (y - 6)(3y + 10) = 0

⇒ y = 6 or 3y + 10 = 0

⇒ y = 6, - 10/3 (Rejecting negative sign's one)

⇒ y = 6

⇒ √x = 6

Squaring both sides, we get

⇒ x = 36

Hence, total number of camels is 36.
