The mean of `1,3,4,5,7,4` is `mdot` The number `3,2,2,4,3,3,p` have mean `m-1` and median `qdot` Then, `p+q=` 4 (b) 5 (c) 6 (d) 7

Explanation

Given: Mean of `1,3,4,5,7 and 4 is m`


`Rightarrow frac{1+3+4+5+7+4}{6}=m Rightarrow m=4`


Given: mean of` 3,2,2,4,3,3 and P` is `m-1`.


`Rightarrow frac{3+2+2+4+3+3+p}{7}=3` `(Given: m=4)`


`Rightarrow 17+p=21=p=4`


For finding median,


Arrange` 3,2,2,4,3,3, and 4` in ascending order,


So, ` 2,2,3 ,3,3,4,4`
