Question

8. 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
​

Answer 1

Step-by-step explanation:

Let the total number of deer be x.

No. of deer gazing in the field = 1/2 of x = x/2

No. of deer playing nearby = 3/4 of remaining (Other half is remaining) = 3/4 of x/2 = 3x/8

No. of deer drinking water from the pond = 9

Therefore,

("The rest 9 are drinking water from the pond." So if you subtract the total no. of deer playing nearby and grazing in field from the total no. of deer in the heard, you will get 9)

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

x - (4x+3x/8) = 9

8x-7x/8 = 9

x = 9*8 = 72

Therefore, total no. of deer in the herd is 72.

Here is your answer. Hope it helps!
