Find the length of the tunnel..

A train 800 metres long is running at a speed of 78 km/hr. If it crosses a tunnel in 1 minute, then the length of the tunnel (in meters) is??


Answers:
500meters


Explanation:

Speed =		78 x	5		m/sec	=		65		m/sec.
			18					3

Time = 1 minute = 60 seconds.

Let the length of the tunnel be x metres.

Then,		800 + x		=	65
		60			3

 3(800 + x) = 3900

 x = 500

What is the age of youngest child??

The sum of ages of 5 children born at the intervals of 3 years each is 50 years. What is the age of the youngest child?

Answer: 

4 Years.

Explanation:

Let the ages of children be x, (x + 3), (x + 6), (x + 9) and (x + 12) years.

 5x = 20

 x = 4.

 Age of the youngest child = x = 4 years.
