 Question 

Ramesh Rao working in a company got a salary increment of 10% for good performance in his job.

After 2 months, company realized that increment was for another employee Ramesh R, and not Ramesh Rao.

An instruction was given to accounts department to reduce the salary of Ramesh Rao by 10% and increase the salary of Ramesh. R. By 10%

From next month, Ramesh Rao started getting a  salary lesser than what he was getting prior to his promotion.

How did this happen and what is the %ge decrease in salary??

Answer 

Let's assume Ramesh Rao's original salary was 100 Rs.

After 10% increment, salary  =  100 +  10% of 100

                                                          = 100  +  10

                                                           = 110 Rs

Then  10% decrease on 110 Rupees.

==>>   Decrease  =  10% of 110

==>>   Decrease  =  11 Rs

Ramesh Rao's new salary  =  110  -  11

  ==>>   New salary  =  99  Rs

Percentage decrease =  ( 100 -  99 )  /100

     ==>>     1%    !!!

Why is there a hole in middle of medu vada ??

 Medu vada is usually thicker in shape.

We can make vada without a hole at the middle  !!!

But at that time, only the outer part of vada gets cooked.  Not the inner part.

By making a hole in the dough and then frying in hot oil makes both the sides to get cooked uniformly and it gets crispy.

Surface area of medu vada increases by making a hole at the middle.  This makes vada to stand steady when frying.

Extra oil which is not needed will flow out easily thereby making the vada smoother and crispy.

Sleeping near doors allows dogs to stay alert to sounds, movements and changes in their surroundings.

Oceans on Enceladus are highly alkaline

Enceladus is one of the satellites of planet Saturn.

 Plumes that emanated from Enceladus' south pole regions , are discharged from geysers.

The plumes are having water vapors,, molecular hydrogen, organic hydrocarbons and molecules of methane, ethane , oxygen and nitrogen.

pH levels of subsurface liquid water ocean is based on phosphate levels in ice grains discharged from Enceladus' plumes..

Researchers estimated that Enceladus' ocean has pH between 10.1 to 11.6 making it highly alkaline.

The carbon dioxide degassing within Enceladus' ocean could increase the pH value when it is discharged via the plumes.

Why Greenland looks bigger on the map than really it is ??

 After annexing Venezuela, now Trump wants to get hold of Greenland  !!!

He said he was open to military actions to occupy this Arctic region from Denmark.

While Greenland dominates political discussions, its visual size on maps is quite misleading.

At first glance, Greenland appears as large as entire continent of Africa  on many world maps   !!!

 In reality, Greenland is 14 times smaller than Africa....

Regions close to poles, like Greenland, Antarctica and Russia are heavily sstretched.

Farther a place is from equator, larger it appears on map  !!!

It is like wrapping a flat paper around a round balloon.  To make it to fit, the edges must be wrinkled or stretched.

But Greenland is the world's largest island   !!!!
