Haha...*flattered* No lah, Muffins, me not that artistic

Just want to share with fellow KiasuParents members that model-drawing is not as difficult as what it seems. In fact, it can be fun and enjoyable too.

I've received a query for the following % questions from Kitty2. Can take a look and see if your children can figure these out...

1. Benny had 20% more marbles than Hong Joo. After Hong Joo had received 80 marbles from Benny, Hong Joo had 20% more marbles than Benny. How many marbles did the 2 boys have altogether?

2. A certain number of stamps was shared between Tony and Jennifer. Tony's share was 600 stamps. If Tony's share was increased to 680 stamps, Jennifer's share would be decreased by 8%. Find Jennifer's share.

3. 25% of the boys and 12% of the girls made up 139 children. There were 660 children altogether. How many boys and how many girls \twere there?

4. Janet had 60% more money than Andy. Helen had half of what Janet had. When Andy gave $240 to Helen, both of them had the same amt of money.\t
