Let M , S and L , be the shares of M a r v i n , S k y and L o r d , respectively. Then
S = 5 0 0 + L ( 1 )
M = 2 0 0 + S = 2 0 0 + 5 0 0 + L = 7 0 0 + L ( 2 )
We know that,
S + M + L = 1 5 0 0
Plug in ( 1 ) and ( 2 ) in the above equation. We have
5 0 0 + L + 7 0 0 + L + L = 1 5 0 0
1 2 0 0 + 3 L = 1 5 0 0
3 L = 3 0 0
L = 1 0 0
