Number of girls on the bus does not change. Number of girls＝35-14 ＝21 After the boys alighted, percentage of girls increase to 70%. 7 units＝ 21 1 unit ＝ 3 Number of boys left on bus＝ 3units (30%) 3 units ＝ 3 x 3 ＝ 9 Numberof boys that alighted ＝ 14-9 ＝5.

Hi all. I found this very interesting Logic question. This would not come out for PSLE for sure, but it would be fun to think over it and let students work on this Q. It might (or it WILL !!) strengthen students' logical thinking skills. (The Q is scary, but not difficult) Note : Just comment "Got it" if you know the answer, so that everyone can try it out.

Wow this is like an extension of geometric progression. Would be easier if they can use a summation symbol.
