Step-by-step explanation:

Let the total number of deers be X.

No. of deers in the forest = 1/4x

No. of deers in the field = 1/3x

No. of deers drinking water = 15

Total number of deers = 1/4x + 1/3x + 15 = x

3/12x + 4/12x - x = -15

7/12x - 12x/12 = -15

-5X/12 = -15

5x/12 = 15 (both minuses gets CANCELLED)

5x = 15 * 12

5x = 180

x = 180/5

= 36

The total number of deers are 36.
