Let the total number of camels be x.

Camels who ran into forest = 1/4 x

Camels who went to the mountain =2 x

Camels who went to the bank of the river = 15

Then,

x = 1/4 x + 2x  + 15

3/4 x = 2x  + 15

3x = 8x + 60

3x - 60 = 8x

On squaring we get

9x2 + 3600 - 360 x = 64 x

9x2  - 424 x + 3600 = 0

 On solving the above equation using quadratic formula,

we get  x = 36 and x = 11.1 (neglected, since number of camels cannot be in fraction)
