The mean of five numbers is 10
i add one more number and the mean is now 11
what number did i add?

Step-by-step explanation:

then ,

a+b+c+d+e = 50

Now, if we add a new number and call it f we will get:

then,

(a+b+c+d+e) + f = 66

then f=66-(a+b+c+d+e) = 66-50=16.

:)

mean of 5 numbers = 10

mean of 6 numbers = 11

therefore, mean= 7 + 13 + 6 + 14 + 10 = 50 =  10

                                       5                         5

if one more number make it 11, then

2x=10

2     2

x=5
