Question

One third of a herd of animals are grazing in the forest and two fifths of the remaining are resting nearby a pond. The remaining six are drinking water from the pond. Find the number of animals in the herd.

Answer 1

Answer:

Let total no. of deer = x

half of herd =x/2

3/4 of remaining half herd =(x/2)(3/4)

                                         =3x/8

remaining deer=9

x=(x/2)+(3x/8)+9

x=(4x+3x+72)/8

8x=7x+72

8x-7x=72

x=72

∴total no. of deer are 72
