Question

The mean of 40,50 and 90 is P. If the mean of 40,50,90 and P is Q. What is the value of Q

Answer 1

Given:-

The mean of 40,50 and 90 is P. If the mean of 40,50,90 and P is Q.

To find:-

The value of Q.

So now the mean of 40,50 and 90 is P. so we get,

`(40+50+90)/(3)=(180)/(3)=60`

So the value of p is 60.

Also we have the mean of 40,50,90 and P is Q. so we get,

`(40+50+90+60)/(4)=(240)/(4)=60`

So the value of q is 60.
