Answer:
36 Camels
Step-by-step explanation:
total number of camels = x
no of camels in forest = x / 4
no of camels in mountain = 2√x
remaining camels = 15
total number of camels = no of camels in forest + no of camels in mountain + remaining camels
x = x / 4 + 2√x + 15 (multiply entire equation with 4)
4x = x + 8√x + 60
3x = 8√x + 60
3x - 8√x - 60 = 0
consider x = a²
so √x = a
3a² - 8a - 60 = 0
3a² - 18a +10a - 60 = 0
3a (a - 6) + 10 (a - 6) = 0
(3a + 10) (a - 6) = 0
a = 6
√x = a = 6
x = a² = (6)² = 36
total number of camels = x = 36 camels
