One day on reaching school I found there were a total of 16 bicycles and tricycles parked in the school compound. I counted the total number of wheels to be 38. Find out the number of bicycles.
10 bicycles.
Explanation:: All the cycles will have at least 2 wheels, so 16 cycles will have 16x2=32 wheels. But in total there are 38 wheels. So the extra wheels (38-32=6) must be of the tricycles because bicycles have 2 wheels and tricycles have 3 wheels.
Therefore, the number of tricycles parked is 6 and hence the number of bicycles is 10.
I started learning to drive today. Just a few minutes back, I went down a one-way street in the wrong direction but I did not break the traffic rules. How?
Let us imagine that you are standing at the southern-most point of the earth. Now on the eastern side of that point is an island and on the western side of that point is a lake. Which one is closer to you - the island or the lake - and why?
