Question 12

The average of 11 results is 182. If the average of first 6 results is 199 and that of the last 6 results is 161, then what will be the 6th result?

Solution

Average of 11 results = 182

=> Sum of 11 results = $$182\times11=2002$$

Similarly, sum of first 6 results = $$199\times6=1194$$

And sum of last 6 results = $$161\times6=966$$

$$\therefore$$ 6th result = $$(1194+966)-2002=158$$

=> Ans - (C)
