  Question 

All mobile numbers in India are 10 digits.

With 10 digit number, how many mobile subscribers can be supported at any time ??

Answer 

In a 10 digit number, each position can be filled by any of 10 digits ( 0 through 9  )

To find the total number, we multiply the number of possibilities for each position.

==>>   10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10

==>>   10  ^  10

==>>    10 billion    !!!

The mathematical answer is 10 billion.

But in India, we have prefix restrictions.

Mobile numbers must start with digits  9   8    7  or  6.

To find the total combination,

For the first digit, we have only 4 possibilities. They are 6  7  8  or  9.

For second digit to last digit, 10 possibilities each ( from  0  to   9  )

==>>    4  *   10  ^   9

==>>   4  billion  !!!

Which Indian city is known as City of Hundred islands ??

 The city of Hundred Islands is in Rajasthan   !!!

When we think of Rajasthan,  we often think about deserts, forts and rugged terrain.

But in the southernmost part of Rajasthan, a different picture emerges, one of green hills, flowing water and tiny islands scattered across river lake.

This is         BANSWARA     !!!!

The city got its name from how the Mahi river's backwaters spread out.

When the water fills the river basin, it breaks up into many small islands that dot the landscape like green dots on water  !!!

The pattern is especially striking in monsoon months.

Why is space dark ??

 Why is space dark if there are so many stars ??

It is known as Olbers' Paradox.

The Universe is expanding 

                 As space stretches, the light from distant stars gets stretched too  !!!  This is called redshift.

                By the time light reaches us, it has turned into infrared or radio waves that our eyes can't see   !!!!

Universe is about 13.8 billion years old.  Light from distanced stars simply hasn't had enough time to reach us yet  !!!
