The question relates to the total number of pairs of feet ducks and a pigs

are known to have.

  • There are 5 pigs and 10 ducks

Reasons:

The length of the group of ducks and pigs = 40 feet

Number of ducks = Twice the number of pigs

  • Each duck has 2 feet.
  • Each pig has 4 feet.

Let x represent the number of pigs, and let y represent the number of ducks, we have;

y = 2 × x

4·x + 2·y = 40

Which gives;

4·x + 2 × (2·x) = 40

8·x = 40

x = 40 ÷ 8 = 5

  • The number of pigs, x = 5

y = 2 × x

Therefore;

y = 2 × 5 = 10

  • The number of ducks, y = 10
