Day 16 – Celebrity maths answer…

Last week I put forward a challenge which virtually all the celebrities in the UK Big Brother house failed to answer correctly. You can read the original post here.

The question was:

And all those who responded were correct with the answer of 120.

Clearly people who blog are more mathematically connected than our celebrity folk.

For those who weren’t sure of the answer, the trick in the question is Divide by Half. This is the same as multiply by 2, so:

50 divide by half then add 20 = 50 x 2 + 20 = 120

Well done to all those who answered.
