Question

5. The mean of 10 numbers is 27. If one of the numbers is excluded then mean gets
reduced by 2. What is the excluded number?​

Answer 1

Step-by-step explanation:

let the sum be x

then x/10= 27

x=270

if one no. is excluded then the new mean is 25

y/9=25

=y= 225

x-y = 270-225

x-y= 45

therefore the no. excluded is 45
