**The average of 11 results is 60. If the average of the first six results is 58 and that of the last six is 63, find the 6th result.**

### Note

The average of 11 results = 60

The total of 11 results = (60 × 11) = 660

The average of the first six results = 58

Average of last six results = 63

Total of first six results = (58 × 6) = 348

Total of last six results = (63 × 6) = 378

**∴ Sixth results = total of first and last six results = total of 11 results**

**= (348 + 378) - 660**

**= (726 - 660)**

**= 66.**
