On a differnet note, what is with the PSLE maths questions anyway?.. look at the questions in uni..are we complaining? haha.. yaya cannot compare.. my friend decided to come up with some questions which he said he will submit it to the examination board for next year's paper:

1) Container A has 5 litres of water, John pours 3 litre of water into container B which is initially empty. After which, John pours 2 litres of water from container B into Container C which contains 4 litres of water initially. As the containers are placed outdoor, they are subjected to the elements. Not long after, it begins to rain.. Rain falls for 10 hours at 3Litres/hour into the containers. How many containers are there?

2) John was shopping when he was robbed. The robber ran for 30 meters and John pulls out his hand gun and fires (time, t= 0). The bullet travels at 100meters/s and the robber runs at 10meters/s. Air resistance increases as the bullet accelerates thus slowing it down at 1meter/s. At time t=4s, the robber grabs a bicycle and pedels at 50meters/s How many letters are there in John's name?

3) MCQ: John was walking home from school and he decided to buy 183 apples at NTUC, not long after Mary came in and bought 999 apples. Peter then came into the store and bought 43 apples. They placed all the apples into a van and went home together. 2 days later, 4/5 of the apples rotted, none was consumed. How many types of fruits are there?

a)one
b)two
c)three
d)None of the above.
