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.
Answer:
The above excerpt is a good example of the many storytelling devices used in 1001 Nights except surprise ending.
Explanation:
<u>The excerpt we are analyzing here does have elements of repetition, dialogue and recurring theme. However, it is not a good example of surprise ending, and the reason for that is very simple. </u>Take a look at how the excerpt ends:
<em>The porter was so dazzled he could hardly believe that he heard her aright, but he shouldered his basket in hot haste, saying in himself, "O day of good luck! O day of Allah's grace!" and walked after her till she stopped at the door of a house.</em>
<u>This is not a proper ending. As a matter of fact, this is the beginning of the story. Readers are left expecting, wondering what happens to the porter and the mysterious woman once they reach that door.</u> It might very well be that the story does have an interesting ending, but we are analyzing the excerpt only. And the excerpt does not have an ending whatsoever.
Answer: D
explanation: the last part of the sentence “she will be here soon” sounds out of place. in order to make it flow, it would need a conjunction such as, because. therefore this makes it the answer.
