The numbers are 1.5, 1.25, 1.2 and 3.16

ya.. thats a good try.
how did you find that out?

I got the answer by trial and error method,

A+B+C+D=7.11
A*B*C*D=7.11

Multiply both sides of the equations by 100

Assume,
a=100*A
b=100*B
c=100*C
d=100*D

You will get
a+b+c+d=711
a*b*c*d=711000000

I proceeded these steps and i got stuck, so i went for trial and error method... I'm trying to get the correct solution... If anyone know jus tell me...

Hey Suresh can u give me the correct solution other than trial and error method...

Sorry manoj....... I didn't know the way of solution...

I got this puzzle in somewhere place.i like this puzzle.that's why i posted here.
