Question

The mean of 11 number is 35 . If the mean of the first 5 number is 32 and that of the last 6 numbers is 37. Find the sixth numbers

Answer 1

Sum of all 11 numbers = 11*35 = 385
Sum of first 6 numbers = 6*32 = 192
Sum of last six numbers = 6*37 = 222

Sum of first six and last six numbers = 192+222 = 414

Sixth number = 414 - 385 = 29
