Question

One fourth of a herd of deer has gone to the forest, One third of the total number is
grazing in a field and remaining 15 are drinking water on the bank of a river. Find the real
number of deer​

Answer 1

Answer:

36

Step-by-step explanation:

let the total number of deer be = x

1/4 gone to forest = 1/4 x

1/3 grazing = 1/3 x

remaining = 15

$\frac{1}{4} x + \frac{1}{3} x + 15 = x \\ \frac{3x + 4x + 180}{12} = x \\ 7x + 180 = 12x \\ 12x - 7x = 180 \\ 5x = 180 \\ x = \frac{180}{5} \\ x = 36$

total number of deers are 36

deer gone to forest = 1/4 × 36 = 9

deer grazing = 1/3 × 36 = 12

drinking water = 15

9 + 12 + 15 = 36
