Have you managed to work out this week's brainteaser yet? It was placed on our Facebook page this morning.

This intelligence test has been doing the rounds on Facebook for quite a while. It seems to be easy for some people and difficult for others. Could you work it out?

If you've come here looking for the answer, then look no further...

This weeks brainteaser asked you to solve the following:

6 + 4 = 210
9 + 2 = 711
8 + 5 = 313
5 + 2 = 37
7 + 6 = 113
9 + 8 = 117
10 + 6 = 416
15 + 3 = 1218
?? + ?? = 123

scroll down for the answer












To work out the answer you need to first split the resulting number "123" into 2 parts - 1 and 23. Those numbers

will be 2 results. "1" will be result of "first number minus second number". "23" will be result of "first number plus second number".

So it's easy to see that those 2 numbers will be 12 and 11.

12 - 11 = 1

12 + 11 = 23

Write them together and you get 123.

So the answer is 12 + 11 = 123.

Was it hard?
