Question

half of herd is grazing three fourth of remaining are playing and rest 9 are drinking water nearby no of deer in herd

Answer 1

According to given sum,


Let the number of deers be x.

Then, no.of deers that are grazing => x/2 .

no.of deers that are playing => 3/4 of x/2

=> 3/4×x/2

$= > \: \frac{3x}{8}$

And the remaining deers => x-(x/2+3x/8)

=> x/8=9

=> x=72.

Hence, the no. of deers in the herd = 72.

:-)Hope it helps u.

Answer 2

The total number of deer =x

Number of grazing deer=1/2x

Number of playing deer=1/2x-3/4x

=3/8x

Number of drinking deer=9/1

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

x/1=4x+3x+72/8

8x-7x=72

x=72

Number of total deer=72
