hello , here is your answer

_,____________________

the weight kept must also be in the same ratio as length of arms
== .................................==
——————-o-————
.......................||..........................
as ratio of lengths of arm
= shorter : longer = 4:6

so ratio of weight must be
shorter : longer = 6:4

this will balance it

100 / longer arm =6/4

$\frac{100}{x} = \frac{6}{4} \\ \\ x = \frac{200}{3} = 66.66$
