There are a total of 18 geese and goats in the field. These animals have 42 feet altogether. How many of each type of animals are there?
- Number of goats?
- Number of geese?
Assuming all are geese,
Number of legs of all the geese
= 18 x 2
= 36
Number of extra legs left
= 42 - 36
= 6
Difference in the number of legs between 1 cow and 1 chicken
= 4 - 2
= 2
(a)
Number of goats
= 6 ÷ 2
= 3
(b)
Number of geese
= 18 - 3
= 15
Answer(s): (a) 3; (b) 15
