**MathMate**, Thursday, May 24, 2012 at 1:08pmUp to #9, you have #6 and #8 are correct.

I will appreciate if you could show how you worked out the remaining numbers so that any incorrect notions could be corrected accordingly.

There is no use throwing a coin to make a guess if you don't know how to get the right answer.

For example, in the first question, the principal is $1604. At 10% for a whole year (instead of two months), it would be approximately 10% more at about $160 in interest. So it is impossible to expect $3208 over two months!

Try calculated guesses if you have to make them.
