A farmer has 120 chickens and goats. The total number of legs is 320. How many goats does the farmer have?

A.30 goats
B.40 goats
C.50 goats
D.60 goats

Kunci jawaban & pembahasan

Jawaban: 40 goats

Let goats = g, chickens = 120 − g. Legs: 4g + 2(120 − g) = 320 → 4g + 240 − 2g = 320 → 2g = 80 → g = 40 goats.
