A man was going to buy a $5000 car, but he didn't pay a penny for the car, how is this possible?



Ans.He didn't pay a penny, he payed $5000 for the car!HaHaa....

1.Quick! Count the num­ber of times that the let­ter F appears in the fol­low­ing sen­tence: “Fin­ished files are the result of years of sci­en­tific study com­bined with the expe­ri­ence of years
How many did you find? Check the solution down!

Ans.How many F's did you count? Three? Wrong, there are six! It's no joke! Read again:

FINISHED FILES ARE THE
         RESULT OF YEARS OF SCIENTIFIC
         STUDY COMBINED WITH THE
         EXPERIENCE OF YEARS

Almost everyone guesses three. Why? It seems that the brain cannot correctly process the word "OF". The letter F usually makes the "f" sound, like in "fox". However, in the word "of", it makes a "v" sound. Somehow, your brain overlooks the word "of" as it scans for the sound of "f".

The Hare and the Tortoise

	Haretown and Tortoiseville are 77 miles apart. A hare travels at 10 miles per hour from Haretown to Tortoiseville, while a tortoise travels at 1 miles per hour from Tortoiseville to Haretown. If both set out at the same time, how many miles will the hare have to travel before meeting the tortoise en route?
	Hint: Are the hare and tortoise together covering the distance at a speed equal to the sum of their individual speeds?  Solution: The hare and the tortoise are together covering the distance at 11 miles per hour (i.e., on adding their speeds). So, they will cover the distance of 77 miles in 7 hours. Thus, in 7 hours, they will meet and the hare will have traveled 70 miles. Alternative Solution through Equations: Note that : Distance = Speed × Time Let t be the time before the hare and the tortoise meet. In t hours, the hare will travel 10 t miles. In t hours, the tortoise will travel 1 t miles. Now, 10 t + 1 t = 77 So, t = 77 ⁄ 11 = 7 hours. Thus, distance traveled by hare before meeting = 10 × 7 = 70 miles.
