half of a herd of deer are grazing in the field three fourth of deer in the field.the rest of 12 deer are drinking water from the pond.find the number of deer in the herd
Answers
Answer:
72
Step-by-step explanation:
Let total no.of deer = x
half of herd =x/2
3/4 of remaining half herd =(x/2)(3/4)
=3x/8
remaining deer=9
x=(x/2)+(3x/8)+9
x=(4x+3x+72)/8
8x=7x+72
8x-7x=72
x=72
∴total no.of deers are 72.
Answer:
Total number of Sheep = 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 Sheep = 72
