COW +GOAT =240

SHEEP+CAMEL =500

CAMEL-GOAT+SHEEP =455

COW+SHEEP =215

FIND THE VALUE OF THE CAMEL??

Cow + Goat = 240 (i)
Sheep + Camel = 500 (ii)
Camel - Goat + Sheep  = 455 (iii)
Cow + Sheep = 215 (iv)

from (iii),
Camel - Goat + Sheep  = 455 Or (Camel+ Sheep) - Goat  = 455
Hence from (ii), we get
500 - goat = 455 or Goat = 45 (v)
Putting (v) in (i), we get
Cow + 45 = 240
Cow = 195 (vi)

putting (vi) in (iv), we get
195 + sheep = 215
Sheep = 20 (vii)

Putting (vii) in (ii), we get
20 + camel = 500
camel = 480
So Camel = 480 (Ans)
