Explanation:
The score of Sachin in consecutive five innings at 80, 90 ,100, 100 and M respectively.
The average of the five innings is 100.
We need to find the value of M.
Average = sum of observations/total no of observations
Sum of observations = 80+90+100+100+M
= 370 + M
Total no. of observations = 5
Put all the values,

So, he scored 130 in his last innings.
He scored (130-80 = 50) more in his last innings as compared to the first inning scored.
According to a different source, this question refers to the poem "Burning a Book" by William Stafford.
In this poem, the author employs a free verse structure in the poem. This means that the author does not follow a strict rhyming pattern. The main theme of the poem is that ignorance and lack of new ideas are great threats to society. He claims that this is even worse than burning a book:<em> "More disturbing than book ashes are whole libraries that no one got around to writing." </em>Therefore, the author encourages innovation, ingenuity and creativity. This is emphasized by the free verse that the author employs.
The CD player buzzed in protest, clearly far too old to be considered useful.
Psychology Major here! :) Hope this helps:
1) Up to date, there is still no definite answer when it comes the capacity of information a brain can withhold - it is truly unlimited.
2) The size of a brain varies between species and its capacity to retain information varies as well.
3) Humans have the most complex psychological process to understand, however, there are many other species who have incredible cognitive intelligence. (Such as dolphins, for example.)
4) When damage is done to a certain side of the brain and there is a need to remove the damaged area, there is a possibility that the undamaged parts of the brain can take over the same functions as the removed area. (Therefore, for example, the remaining part of your brain can still nearly function to a maximum capacity depending of the severity of damage... as well as area).
5) The brain named itself "brain".
(The brain controls you, but you control the brain.)
