z One-fourth of a herd of camels was seen in the forest. Twice the square root of the herd hadgone to mountains and the remaining 15 camels were seen on the bank of a river. Find the totalnumber of camels.

Answer»

Answer: 36

Step-by-step explanation: let the number of camel is x

Number of camels was seen in the forest = x/4

Number of camels had gone to the mountains = 2√x

number of camels were seems on the bank of river = 15

so, total number of camels = x/4 + 2√x + 15 = x

or, 2√x + 15 = 3x/4

or, 8√x + 60 = 3x

or, 64x = 9x² + 3600 - 360x

or, 9x² + 360x + 64x + 3600 = 0

or, 9x² + 424x + 3600 = 0

After solving with help of formula to find root of quadratic equation

We get, x = 36 and 100/9

Hence, number of camels = 36
