Pigs = ½ of goats = 140 x ½
= 140 ÷ 2
= 70
Cows = 2 x (goats + pigs)
= 2 x (70 + 140)
= 2 x 210
= 420
Chickens = 2½ x cows
= 420 x 2½
= 1050
Ducks = ½ x (chickens + cows + goats + pigs)
= ½ x (1050 + 420 + 140 + 70)
= ½ x (1680)
= 840
Total = 1680 + 840
= 2520
= 140 ÷ 2
= 70
Cows = 2 x (goats + pigs)
= 2 x (70 + 140)
= 2 x 210
= 420
Chickens = 2½ x cows
= 420 x 2½
= 1050
Ducks = ½ x (chickens + cows + goats + pigs)
= ½ x (1050 + 420 + 140 + 70)
= ½ x (1680)
= 840
Total = 1680 + 840
= 2520
