Options:

28

29

30

27

Correct Answer:

29

Explanation:

Mean of 11 numbers = 35

Sum of 11 numbers = 35*11 = 385

Mean of first six numbers = 32

Sum of First Six Numbers = 32*6 = 192

Mean of last six numbers = 37

Sum of last Six Numbers = 37*6 = 222

Thus 6th number = (222+192)-385 = 29

The correct answer is Option (2) → 29
