The above given fig.is the one for your question....

Let's say the weight off the scale is W then...

Total Clockwise moment=

(40 × 20)=800......1

Total Anti-clockwise moment=

(5×50)+(W×10)=250+W10........2

We know,Total clockwise moment=Total anti-clockwise moment

so...

250+W10=800

or,W10=800-250

or,W10=550

or,W=550÷10

hence W=55gf

There you go!
