one FOURTH OF A HERD OF CAMELSWAS SEEN IN THE FOREST .

Question

TWICE THE SQUARE ROOT OF YHE HERD HAD GONE TO MOUNTAINS AND THE REMAINING15 CAMELS WERE SEEN ON THE BANK OF THE RIVER .

FIND THE TOTAL NO. OF CAMELS

Answer 1

went in forest: 1/4 x
in mountain: 2\sqrtx
x - 1/4x - 2\sqrtx = 15
3/4 x - 2sqrtx = 15
square both sides
9/16x^2 - 4x = 225
divide both sides by 9/16
x^2-64/9x = 400
x^2 - 64/9x -400= 0
use factoring

Answer 2

or u could guess seeing that a camel cannot be split into quarters or sqrts. thus it must be a number less than 100 which is a square and divisble by 4...so the answer is 36
