Answer:
The answer for this question is=72
Explanation:
Step-1:-Let the total no.of deers=x
Step-2:-Deers grazing in the field=1/2 of herd of deer
=1/2×x
=x/2
Step-3:-Remaining deers =x/2
Step-4:-No.of remaining deers playing=x/2×3/4
=3x/8
Step-5:-No.of deers drinking water=9
Step-6:-So,Deers grazing in the field+deers playing+deers drinking water=Total no.of deers
Step-7:-Hence,x/2+3x/8+9=x
Step-8:-So,4x+3x+72/8=x
Step-9:-Therefore,7x+72=8x
Step-10:-Now, 72=8x-7x
Step-11:-Then, 72=x
