If the mean of five observation `x , x+2, x+4,x+6, x+8` is 11, find the mean of first three observations.

If the mean of five observations x , x + 2 , x + 4 , x + 6 , x + 8 is 11, find the mean of first three observations.

Assertion : If the mean of five observations x, x + 2, x + 4, x + 6, x + 8 is 11, then mean of last three observations is 8. Reason : Mean of n observations is equal to Sum of observations upon Number of observations

If the means of five observation x, x + 2, x + 4, x + 6, x + 8, is 11 then the mean of first three observation is

If the mean of five observations x,x+2,x+4,x+6,x+8 is 11, then the mean of first three observations is 9 (b) 11 (c) 13(d) none of these

True/false If the mean of 5 observation x,x+2,x+4,x+6,x+8 is 11, then the mean of first three observations is 8.

If the mean of five observations x, x + 2, x + 4, x + 6, x + 8 is 11, then the mean of the first three observations is

If the mean of five observations x ,\ x+2,\ x+4,\ x+6,\ x+8\ i s\ 11 , then the mean of first three observations is 9 (b) 11 (c) 13 (d) none of these

If the mean of observations x,x+2,x+4,x+6 and x+8 is 11, find : the mean of the first three obervations.
