PSLE: Dear students, Do not STRESS; Do your BEST; Forget the REST. "You may never know what results come of your action, but if you do nothing there will be no result.” ~ Mahatma Gandhi.


1. MAN WITH A FOX: A man went on a trip with a fox, a goose and a sack of corn. He cam upon a stream which he had to cross and found a tiny boat to cross the stream. He could only take himself and one other - the fox, the goose or the corn at a time. He could not leave the fox alone with the goose or the goose alone with the corn. How does he get all safely over the stream?

2. THE CAKE:  Mary takes fruit, cake and cookies for her picnic. She has three boxes for them - one is labelled COOKIES, one is labelled CAKE and one is labelled FRUIT. Mary likes to fool everyone so she has put every single thing in the wrong box. At the picnic, he tells everyone that the fruit is not in the CAKE box. Where is the CAKE?

3. THE SWITCH: You are standing in front of a room with one light bulb inside it. You cannot see if it is on or off. Outside the room there are 3 switches in the off positions. You may turn the switches any way you want to. You stop turning the switches, enter the room and know which switch controls the light bulb. How?

4. KIND POLICEMAN: A policeman saw a truck driver go the wong way down a one-way stret, but made no attempt to stop him. Why?

5. TWO THREES: Obtain twenty using two threes. You can use any mathematical sign or operation.

5. Use both the factorial sign ! and decimal sign as shown here: 3!/.3=20

4. The truck driver was on the foot

3. The Switch: You turn 2 switches "on" and leave 1 swtch "off" and wait about a minute. Then enter the room, but just before you enter, turn one switch from "on" to "off". Once in the room, feel the light bulb - if it is warm, but off, it has to be the last switch you turned off. If it is on, it has to be the switch left on. If it is cold and is off, it has to be the switch you left in the off position.

2. The Cake: The cake is not in the CAKE box, and it cant be in the COOKIE box, because that's the only place for the fruit. So it must be in the box labelled FRUIT.

1. Man with a fox: Take the goose over first and come back. Then take fox over and bring the goose back. Now take the corn over and come back alone to get the goose. Take the goose over and the job is done!
