let the half no of deer be x

grazing=x

playing=3/4 of x

=3x/4

drinking water=9

total no of deer=2*x

=2x

2x=x+3x/4+9

2x-x=3x/4+9

x-3x/4=9

x/4=9

x=36

2x=72

therefore total no deer are 72

Answer:

the number of deers in the herd are 72

Step-by-step explanation:

let the number of deers in the herd = X

no. of deers grazing in the field = X/2

no. of deers playing nearby = 3/4 of X/2

                                           = (3/4)(X/2)

                                           = 3 X / 8

no. of deers drinking water from nearby pond = 9

according to the question,

9 + X/2 + 3 X / 8 = X

9 + 4 X/8 +3 X/8 = X

9 + 7 X/8 = X

9 = X - 7 X/8

9 = 8 X/8 - 7 X/8

9 = X/8

X = 8×9

X = 72

total number of sheeps = 72
