A crocodile's tail weighs 30kg. Its head weighs as much as the tail added to one half of the combined weight of its body and legs. The body and legs together weigh as much as the tail and head combined. What is the total weight of the crocodile?
A 220 kg
B 240 kg
C 260 kg
D 280 kg
Please help to explain the above question, much thanks
t = 30
h = t + (1/2)(b+L)
(b+L) = t+h
we want W = (b+L) + t + h
=============
W = 2 (b+L)
(b+L) = 30+h
h= 30 +(1/2) (30+h) = 30 + 15 + h/2 = 45 + h/2
h/2 = 45
h = 90
(b+L)= 30+90 = 120
w= 2(b+L) = 240
