Mean of 3 numbers is 10 more than the least of the numbers and 15 less than greatest of the

suppose three numbers be x,y,z
acc. to ques median is 5
so y=5(because median is value of (n+1)th term if n is odd after arranged them in ascending or descending order)
where n is no. of element here n=3
mean=(x+5+z)/3=x+10 and (x+5+z)/3=z-15.

on solving we get
x=0,z=25
So,SUM=0+5+25=30

let three numbers be x,y,z and arranged in value order.
Given median is 5
so y=5.
mean=(x+5+z)/3=x+10 and (x+5+z)/3=z-15.

solving equation we get
x=0,z=25

sum=30

let three no. be a,b,c
mean x
where a smallest and c largest
accrdng to qustn
x/3=10+a;
x/3=c-15;
10+a= c-15;
25 =c+a;
median is 5 (given)
hence 5 can be any no.
a+b+c=25+5
=30 answr

three nos are 0 5 and 25... and their sum is 30

Let the mean of the three numbers be x.

Now as per the criteria mentioned in the problem,

the least number must be = x-10

the greatest number must be = x+15

now the median value is given which is the middle number if the set is sorted which is = 5

Therefore , we can say,

((x-10)+5+(x+15))/3=x

solving we get, x=10

Therefore, the sum is 30.

Mean of 3 numbers is 10 more than the least of the numbers and 15 less than greatest of the 3. If the median of 3 numbers is 5, Find the sum of the 3 numbers?
