Question

one fourth of herd of goats was seen in the forests.twice the square root of the number of the herd had gone up the hill and the remaining 15 goats w ere on the bank of river.find the total number of goats.

Answer 1

there must be 36 goats.

Answer 2

according to question
x/4 + 2√x + 15 = x
3x/4 - 15 = 2√x
9x² - 424x + 3600 = 0
x = (424  + 224)/18 or (424 - 224)/18
x = 36 or 100/9
no.of goats can not be fraction ,hence
x = 36 goats
