Half of the deer herd is grazed in the field and the remaining three-quarters are playing nearby. The remaining nine are drinking water from the pond. The number of deer in the flock is:

A
B
C
D

Solution:

Concept: First, let's assume that the number of deer in the flock is

Then divide the number of deer in the herd by

to find half of the herd grazing in the field. Then find the remaining herd by subtracting half of the herd from the number of deer and taking

. Play the other half th and get the acquisition value equal to 9 to find the value you need.
Let the total no of deer be

So, we have

Thus,

deer in the herd.
Hence, the answer is option 1.
