Question

The mean of 6 number is 19. on excluding one number mean become 18. find the value of excluded number please help urgent

Answer 1

Answer:

The mean of 6 numbers = 19.

So the sum of the 6 numbers = 6 x 19 = 114.

One number is excluded.

The mean of 5 numbers = 18.

Or the sum of the 5 remaining numbers = 5 x 18 = 90.

So the number that has been excluded = 114 – 90 = 24.

Hope it helps you!!
