GMAT Data Sufficiency (DS) | Re: Machines A and B each produce tablets at their respective co

Hi MacFauz,

I see how you come up with the two equation but how that leads to the solution is still rather unclear. The question ask'sHow many tablets does Machine A produce in the time that it takes Machine B to catch up?

Don't you need to know the individual rates to come to the conclusion? These statements are giving us the relative rates, which is fine but how can you tell how long it'll take machine B to make 30 additional tablets without knowing the difference between the twoand the rate of A?
