Internal Table Fields - Multiply ?

Hi Friends,

I havea requirement inwhich i need to multiply the field vales of two different internal tables & display them.

ITAB has fields A,B,C,D,E Having values 10,20,30,40,50 and

JTAB has fields F,G,H,I,J having values 2,4,6,8,10

Now I ned to multiply A & F & I should get output 20.

similarly for B & G i should get output 80.

thanks in advance.

I promise to reward.
