Question

half of a herd of deer are gazing 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

Answer:

Hi here is the answer

Step-by-step explanation:

Let the total number of deer be 'x'

Number of deer grazing in field = 1x/2.

Number of deer playing nearby = 3/4 of 1x/2 = 3x/8.

Number of deer drinking water = 9

ATQ,

1x/2 + 3x/8 + 9 = x

> (4x + 3x + 72)/ 8 = x

> 7x + 72 = 8x

> 8x - 7x = 72

> x = 72

Hence, the total number right deer in the herd is 72.

Answer 2

Answer:

Let the Total deers be "x"

than it is given in question that 1/2*x are grazing____(1)

than remaining are 1/2*x deers_____(2)

in second sentence it is given that 3/4th of remaining(1/2*x) are playing_____(3)

9 are drinking water____(4)

So according to question the equation formed::

x= (1)+(2)

or

x=(1)+ (3)+(4). shown above (2)= (3)+(4)

⬇️

x=1/2*x+(3/4*1/2*x)+ 9

x=x/2+3x/8+9

x=4x/8+3x/8+9

x=7x/8+9

-9=7x/8-x

-9=7x/8-8x/8

-9= -x/8

-9*8= -x

-72= -x

x=72

ANS IS 72
