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.

Five examples of questions:
Dost thou know who made thee? (from "The Lamb")
Little Lamb who made thee? (from "The Lamb")
What immortal hand or eye, Could frame thy fearful symmetry? (From "The Tyger")
In what distant deeps or skies,/ Burnt the fire of thine eyes? (from "The Tyger")
On what wings dare he aspire?/ What the hand, dare seize the fire? (from "The Tyger")
The tone of "The Lamb" is quiet. It asks the questions in a polite and gentle way. It is beautiful and innicent. On the opposite side, "The Tyger" has a tone full of fear and force.
