The number of chickens and pigs are at the farm is 180 and 40 respectively.

Given that,

  • There is a total of 220 chickens and pigs.
  • And, the number of legs of the stock in the farm totals 520.
  • Let us assume the chicken be x and the pigs be y.

Based on the above information, the calculation is as follows:

x + y = 220 ........(i)

2x + 4y = 520 ........(ii)

Multiply by 2 in equation so

2x + 2y = 440

2x + 4y = 520

-2y = -80

y = 80

x = 220 - 80

= 180

Therefore we can conclude that the number of chickens and pigs are at the farm is 180 and 40 respectively.
