The mean of 11 numbers is 35. If the mean of first six numbers is 32 and that of the last six numbers is 37, then the 6th number is: |
28 29 30 27 |
29 |
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 |
