If 3*a = 0 then a has to be zero.

So, 8a = 6b = 0, hence b must also be zero.

So, a = b.

Asked: If 8a = 6b and 3a = 0 then

3a=0 => a=0
8a=8*0=0=6b=> b=0
a=b=0
a & b are equal

IMO A

so b=0
hence a=b=0
IMO A:

Since $$3a = 0$$ ; $$a = 0$$

Now, $$8a = 6b = 0$$. Thus, $$b = 0$$, Answer must be (A) a and b are equal

Since 3a = 0, then a = 0, and 8a = 0. Thus, 0 = 6b, and b = 0.
