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

Use nos

Statement 1 -let Digit r=x9y and digit t=888 so X could be 9 or 7 or some other no hence not sufficient
Statement 2- 10's digit is less than either of the 2 digits of R eg 656 or 746 hence not sufficient

combined

eg r=898 and t=888 hence r>t and both statements together are sufficient.
