Question

1/4th of a herd of cow have gone to the forest.1/3rd of the total no. of cows r grazing in the field and the remaining 15 r drinking water.Find the total no. of cows.

Answer 1

let total no. of cows be x
atq
$\frac{1}{4} x + \frac{1}{3} x + 15 = x$
taking lcm
$\frac{3x + 4x + 180}{12} = x$
$7x + 180 = 12x$
$5x = 180$
$x = 36$
hence no. of cows=36
