Hint
How many bricks are laid in six hours?
Answer
1 hour.
Reasoning
How many bricks are laid in six hours?
In six hours, Kevin lays 1000 bricks, Freddie lays 2000 bricks, and Jimmy lays 3000 bricks.
So in six hours we have a total of 6000 bricks laid.
Which means that it will take one hour to lay 1000 bricks.

Hint
A little algebra might help.
Answer
I will be 35 in 14 years.
Reasoning
I am currently 21.
If X is my current age, then:
X = 14 + X
—
3
so
2X = 14
——
3
and
2X = 42
So
X = 21
I am currently 21 and my favourite book is currently 14 years old, when it is 28 years old (double its age) I will be 35.
