GMAT Data Sufficiency (DS) | If r and t are three-digit positive integers, is r greater than t ?

If R = 100a + 10b + c, and T = 100d + 10e + f, then
From the 1st statement it follows that b>d, b>e, and b>f, however a and c are not given - NS
From the 2nd statement: a > b, and c > b, hence a > d, e, f and c > d, e, f but b is not given - NS
From both statements:
100a+10b+c > 100d + 10e + f
