addition of numbers=56x3

-> let second no.= X.

-> is half of Third i.e, Third No. = 4X.
-> 2X+X+4X=168

Answer / anindya ghosh
If 1st Number =x
2nd Number =x/2
3rd Number =2x
1/3(x+x/2+2x)
=1/3(2x+x+4x/2)
=1/3*7x/2=7x/6
7x/6=56
=>x=56*6/7=48
So. 1st Number = 48 and
3rd Number = 2x=96
Their difference= 96-48 = 48 answer.
