Giving it a try,

Let \"u\" be the unit that Robert gave Albert.
After giving Albert \"u\" from his 124 extra ones, Robert should have 36 more
So,
124-u = u+36
u=44

So Robert has to give 44 paper cranes

Hi rrjan

Qn 1)Arrange 16 coins on 4 sides of a square so that there are 5 coins on each side. Draw on a square to show your answer.

Qn 2)Mike has enough money to buy 2 pairs of socks. There are 3 pairs on display: blue, green and white. How many ways can Mike buy 2 different pairs of socks?

3 ways - 1 B+G 2 B+W 3 G+W

Qn 3)There are 11 persons who work at the fast food restaurant on weekends. 9 of them work on Saturday and 7 work on Sunday. How many persons work on both Saturday and Sunday?

O O O O O O O O O O O O
|-------------------------| 9 work on Sat
|------------------| 7 work on Sun
|------------| Therefore 5 work on both Sat and Sun.

I may be wrong. Get a second opinion.
