Can you crack this tricky puzzle?

Do you enjoy solving puzzles that appear on the internet especially tricky math questions?  If yes this puzzle is a great test of your thinking skills.

Look at the numbers carefully and try to find the missing number in the final line. You have just 15 seconds to solve it.

The puzzle shows:

1 + 3 = 34

5 + 2 = 27

3 + 5 = 58

2 + 4 = ?

At first the answers may look confusing. But there is a simple pattern behind them.

In the first line, 1 + 3 = 4. The answer is then placed after the second number creating 34.

In the second line, 5 + 2 = 7, which becomes 27 when 7 is placed after 2. Following the same pattern, 3 + 5 = 8, giving 58.

Using the same rule, 2 + 4 = 6, so the final answer becomes 46.

Answer: 46
