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.
The correct answer is C. After two such nights, he must be so tired as to be able to sleep anywhere.
Explanation:
The sentence "After two such nights must be so tired as to be able to sleep anywhere" is a fragment because this sentence contains a predicate "must be so tired..." but does not contain a subject, which is an essential element in a complete sentence. In this context, to correct this sentence and make it a complete sentence it is necessary to add a subject such as "he". This correction is shown by option C that specifies who is the agent of the action.
