Answer / swapnil
addition of numbers=56x3
=168
-> let second no.= X.
-> then First is twice the second i.e, First No. = 2X.
-> is half of Third i.e, Third No. = 4X.
-> 2X+X+4X=168
-> X=168/7
=24.
->then no's are
First =2x24=48
Second no =24
Third no=4x24=96.

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.
