There are four animals: Cow, Sheep, Goat, Camel. Their total number is 240. The number of goats and camels is 500. The number of camels and sheep difference is 455. The number of cows and goats is 215

Let C = Cow, S = Sheep, G = Goat, M = Camel.
The given equations are:

1. $C + S = 240$
2. $G + M = 500$
3. $M - S + G = 455$
4. $C + G = 215$

From equation (2):

$$G = 500 - M$$

Substitute $G = 500 - M$ into equation (3):

$$M - S + (500 - M) = 455$$ $$500 - S = 455$$ $$S = 500 - 455$$ $$S = 45$$

Substitute $S = 45$ into equation (1):

$$C + 45 = 240$$ $$C = 240 - 45$$ $$C = 195$$

Substitute $C = 195$ into equation (4):

$$195 + G = 215$$ $$G = 215 - 195$$ $$G = 20$$

Substitute $G = 20$ into equation (2):

$$20 + M = 500$$ $$M = 500 - 20$$ $$M = 480$$

The value of the camel is 480.
