In farmer Brown's hay loft there are a number of animals, in particular crows, mice and cockroaches.
Being bored one day, I decided to count the animals and found there were exactly 150 feet and 50 heads in total, and there were twice as many cockroaches as mice.
10M = 50
M = 5
So we have 5 mice (and 10 cockroaches). We can use M = 5 in (1) to give:
B + 3 x 5 = 50
B + 15 = 50
B = 35
So, C = 10, M = 5 and B = 35. Checking that 10 + 5 + 35 = 50, and 10 x 6 + 5 x 4 + 35 x 2 = 150.
