If the average of s number is r⁴ and the average r
number is s⁴, then find the average of all r+ s numbersSolution
The average of the s number is = r⁴ total sum of s number = r⁴ × s and the average of r number = s⁴ total of r number = s⁴ × r so now the average of r +s number = (r⁴ × s + s⁴ × r )/ r + s = r s (r³ +s³)/r +s =r s (r+ s) (r² +s² -r s)/r + s =r s (r² +s² -r s)
