A train travels at a particular speed for a duration of one hour, after which one of its engine malfunctions reducing its speed to 3/5th of the actual speed before theoccurrence of fault in engine. It travels at this speed for 2 hours to reach at itsdestination. If the fault had occurred 50 miles later on, the train would have reachedits destination 45 minutes early. Find the distance traveled by the train.
Let the actual speed of train be X miles/hour. after fault its speed will be reduced to 3X/5 miles/hour. If we could find the speed of the train, we will get the solution!!!by seeing one can find that
A rich merchant had collected many gold coins. He did not want anybodyto know about them. One day, his wife asked, "How many gold coins do wehave?"After pausing a moment, he replied, "Well! If I divide the coins intotwo unequal numbers, then 37 times the difference between the twonumbers equals the difference between the squares of the two numbers."The wife looked puzzled. Can you help the merchant's wife by findingout how many gold coins?
37(x-y) =x^2-y^2. You no that x^2-y^2=(x-y)(x+y).So (x-y) cancels on both sides to give x+y=37.so sum of unequal halves=37 which is the req answer.

There is a wood and there are birds on each tree. There are number of birds on each tree as many trees in the wood. Number of birds in wood is between 2000 and 2100.FInd total number of trees in the wood.
No. of birds on each tree = Total no. of trees= xNo. of total birds= no. of birds on each tree * total no. of tress No. of total birds= x* xsquare(x)=between 2000 and 2100therfore x= total no. of trees
