Half of a herd of deer are grazing in the field and three fourths of the remaining are playing nearby. The rest 9 are drinking water from the pond. Find the number of deer in the herd.

Let the number of deer be x

The no. of deer grazing in the field= half of x = x/2

No. of deer remaining = x - x/2

The no. of Deer playing in the field = three-fourth of remaining deer = 

The no. of Deer drinking water = 9
