Answer: There are 30 goats in the farm.
Solution:
1. Add the numbers in the ratio
4 + 3 + 2 + 1 = 10
2. Divide 100 and the sum of the numbers in the ratio
100 ÷ 10 = 10
3. Multiply the quotient to each number in the ratio
4 × 10 = 40 (number of chickens)
3 × 10 = 30 (number of goats, ANSWER)
2 × 10 = 20 (number of cows)
1 × 10 = 10 (number of carabaos)
