Question

one fourth of a herd of Deer have gone to the forest. One third of total number are grazing in the field and remaining 15 are drinking water on the bank of a river. Find the total number of deer. Please give me answer please

Answer 1

ok let the number of the deer be X
the equation of problem is as follows
$\frac{1}{3} x + \frac{1}{4} x + 15 = x \\ \frac{7x}{12} + 15 = x \\ \frac{7x - 12x}{12} = - 15 \\ - 5x = - 180 \\ so \: the \: number \: of \: deers = x = 180 \div 5 = 36$

Answer 2

Answer:

36

Step-by-step explanation:

Let the total number of deers be 'x'.

⇒ Number of deers went to forest = (x/4).

⇒ Number of deers grazing the field = (x/3).

⇒ Number of deers on the bank or a river = 15.

Now,

⇒ (x/4) + (x/3) + 15 = x

⇒ (x/4) + (x/3) - x = 15

⇒ -5x/12 = 15

⇒ -5x = -180

⇒ x = 36.

Therefore,total number of deer = 36.

Hope it helps!
