Answer / jyoti
let the third no be x ,
then the first no is 3x ,
second no is 2*3x ie 6x
average is (3x+6x+x )/3 = 20
10x/3 = 20
x= 60/10 = 6
third no is 6 , second is 6x = 36, first no is 3x = 18
largest no is 36 i.e second no

Answer / risha ramanathan
let 1st number be x
thus 2nd number is 2x
let 3rd number be y
since 1st number is thrice the 3rd number, thus
x= 3y
now : 1st no = 3y
2nd no = 6y
3rd no = y
so, (3y+6y+y)/3=20
y = 6
since 2nd no is 6y, therefore 6y = 36
so the 2nd number is the greatest :D

1=3y
2=6y
3=y

or,y=6
then the greatest no. is the second no. i.e. 36

Answer / 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
