IQ Test
Are u Ready?
U Sure??!
Warning: Attemping too hard when u cant do it might kill brain cells...
Coz mine suffered though I managed to get ONE correct only !!
But Have Got The Answers though....
U Sure U Ready??!
Hahar !!
Ahem !!
ok...
Here It goes....
1) Lightbulbs
There are two rooms side by side. From one room you cannot see what is going on in the other. In room 1, where you are standing right now, are 3 switches. These 3 switches would on 3 lightbulbs in the other room. The connections between switch and bulb are completely random. You are only allowed one trip to the other room to try to find out which switch turns on which bulb. The bulbs are all off at the moment.
How?
2) Across the bridge
There are two islands, and a bridge between the islands. On one island stands four people. They all take a different time to cross the bridge - 10 min, 5 min, 2 min and 1 min.
However, there is only ONE torch amongst these people, and they HAVE to use the torch to get across the dark bridge. The bridge, being rickety and all, can only hold a maximum of 2 people at one time, or it will break.
How long will it take for everyone to get to the other island, and how? (no tossing torch across the waters!)
3) Square pool
I have a swimming pool (alright I don't, but hypothetically speaking) which is in the shape of a square. For fengshui reasons, I have a tree planted at each corner of the pool.
I want to double the surface area of the pool with two criteria: The fengshui trees must remain where they are, and the shape of the final pool must remain a square.
How? (cannot increase depth!)
4) Safe sex
There are 2 guys and 2 girls. The 2 guys want to fuck the 2 girls (ie each guy screws both girls) but there is a problem ... There are only two condoms available. Use the condoms any way you want - reuse, flip it, etc - but you cannot wash it.
No body fluids can be exchanged (even girl-girl or guy-guy exchanges), else the sex would not be considered safe from STDs.
How can the task be done?
