Contrastive distribution occurs when two sounds placed in the same context produce different meanings. This is the case in the sounds [k] and [x] . For example: <em>[kano] 'do' versus [xano] 'lose'.
</em>
The same happens with the sounds [ç] and [c]. They are in constrastive distribution as in shown in the following example: <em>[çino] 'pour' versus [cino] 'move
</em>
In complementary distribution, where one sound occurs the other cannot. This is the case in the sounds [k] and [c] The first sound (palatal stop) appears before front vowels whereas the second sound (velar stop) appears elsewhere.
The sounds [ç] and [x] are also in complementary distribution. As in the previous example, the palatal appears before front vowels and the velar appears elsewhere
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.
