This is a real brain teaser.
Question
If 1 + 4 = 5
2 + 5 = 12
3 + 6 = 21
Then
What is 8 + 11 = ???
Answer
Such type of questions follow a definite pattern.
If we closely observe, we can tell that
1 + 4 = 5
=> 1 + ( 1 * 4 ) = 5
2 + 5 = 12
=> 2 + ( 2 * 5 ) = 12
3 + 6 = 21
=> 3 + ( 3 * 6 ) = 21
In the same way,
8 + 11 = ??
=> 8 + ( 8 * 11 ) == 96
