Question

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.

plz answer this one​

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 deers are 72.
