the third no.Their avg is 20.Find the greatest no?
Answer Posted / umeshprabhu
Let the first no be X
Second number is therefore 2x
third number is X/3
THE AVGE OF ALL 3 IS 20
therefore,
(x+2x+x/3)/3=20
10x=180
therefore, x=18
first number is 18
second number is 36
third number is 6
therefore the greatest no is 36
