Question is essentially asking whether r > w.

From stmt1: r/(b+w) > w/(b+r)
adding 1 to each side,
(r+b+w)/(b+w) > (r+b+w)/(b+r)

or (b+w) < (b+r)
or, w < r and hence, sufficient.

Stmt2 does not help get this.

Question is essentially asking whether r > w

how can we say this scthakur ?

the original question is r/(b+w) > w/(b+r)
how do we know that the denominator is not essential here ?

Thanks

The original question is r/(b+r+w) > w/(b+r+w) and since the denominator is the same, r > w.
