mean of 10 observations is 18
sum of observations=10×10=180
if 2 is added to each observation =10×2=20

=180+20
=200
then new mean =200÷10
=20
new mean is 20

HEY Buddy....!! here is ur answer

Given that : The mean of 10 observations = 18

Then Sum of observation = 10×18 = 180

Also given that : 2 is added in each observation it mean 2×10 = 20 is added in sum of observations

Then, 180+20 = 200

Now, new mean = 200/10

=> Mean = 20

Thus, the new mean will be 20

I hope it will be helpful for you...!!

THANK YOU ✌️✌️
