Answer 1

Answer:

There are 5 goats and 15 chicken with the farmer  (1). Pls mark me as brainliest. Aapki bahut kripa hogi.

Step-by-step explanation:

Let the number of chicken be c and number of goats be g

Chicken and goat both have 1 mundi, but chicken has 2 legs and goat has 4.

So, c + g = 20

c = 20 - g   ...1

2c + 4g = 50

2(c + 2g) = 2(25)

c + 2g = 25

20 - g + 2g = 25   [from 1]

20 + g = 25

g = 25 - 20

g = 5

c = 20 - g = 20 - 5 = 15
