Question

Each sheep has 4 legs and each chicken has 2 legs.if a farm boy counts 50 heads and 130 feet, how many sheep are there

Answer 1

15 sheep

Explanation:

1 leg = 1 foot

1 head = 1 animal

Suppose all the animals are chickens:

50 × 2 = 100

130 - 100 = 30

4 - 2 = 2

30 ÷ 2 = 15

Hence, there are 15 sheep.
