Thanks everyone who participate in the contest.
There were 8 right answer this time =D
The right answer was :
From the first equation we find the value of a pair of the bear with the hat as 7.
From the second equation we find the value of each bus with bear as 6.
From the third equation we find that each hat value 2.
Last equation are:
Bear + 2 Hats X 1 Bus with no bear.
If we translate that to numbers we have:
(7-2) + 2x(2) x (6- [7-2]) = ?
Result = 5 + 4 x (6 - 5) = 5 + 4 x 1 = 9
Hope everyone is clear with the explanation...
