When 10 is subtracted from each of the given observations,the mean is reduced by 60%. If 5 is added to all the given observations,the mean will be:

When 60 is subtracted from 60% of a number, the result is 60. The number is :

When 60 is subtracted from 60% of a number, the result is 60. The number is

If the mean of the data 12, 8, 6, 3, 9 is 7.6. If 5 is added to each observation, then the new mean is

Statement (L): Mean (barx) = Sum of the observations // Total number of observations . Statement (M) If a certain number is added or subtracted to the given observations then the mean will change accordingly.

If the mean of 8 observations be 15 and 2 be added to each observation, then the mean of new set of observations will be .

The mean of 5 observations is 3 and if one more observation is added, the mean becomes 3 . 5. Find out the value of new observation .
