Here are two more, courtesy of www.brainbashers.com -

1. Find a number whose double exceeds its half by exactly 99.

2. A haulage contractor did not have room in his garage for 8 of his trucks. He therefore increased the size of his garage by 50 percent, which gave him room for 8 more trucks than he owned altogether. How many trucks did he own? [Note - He did not buy any more trucks after rebuilding his garage]

Cheers!

1) An easy one. You can easily solve it by using an equation, as below:

2 X+  ½ X = X + 99

Which means:

4 X + X - 2 X = 99 ---> 3 X = 99 ---> X = 33

And since X = ½ N

N = the number we are looking for.

The number is 66.

another explanation for the quizz

2X+1/2X=99

3/2X=99

-->X=66

Yes. That way you don't need to make the (x2) at the end.
