S1  r=s=1, therefore r+s=2; rs=0; r x s=1; r/s = 1 hence greatest is r+s. S2  rs is the least. When r=s=1, r+s is greatest. Suppose, when r=3,s=2 r+s=5; rs=1; r x s=6; r/s = 3/2 which gives r x s as the greatest. Since we get two different values, so B not sufficient. Hence answer is A.

the best way to solve the problem will be to assume numbers and A fits nicely

Hi, correct Answer is option D. Even though I don't know why. I was reviewing my answers on the mock test and it showed option A as wrong answer. Anyone here who knows the reason why D is the right answer? (P.s. can't upload image because I'm a new user)

1) r=s=1 clearly r+s is greatest for these values 2)rs is the least of the numbers cant say eg r=s=0.5 r=s is greatest r=s=3 r*s is the greatest not sufficient

Is there a better way to solve the second statement? Using numbers as examples takes time and leaves rool for making error

Using numbers as examples takes time and leaves rool for making error For Statement 1, solving for r+s, rs, rs and r/s clearly indicates r+s as the largest number. For Statement 2, lets assume the following cases. Case 1: r is +ve, and s is +ve=> r+s and r*s is definitely bigger than rs => but its hard to discern which one will be the largest. =>Please note, you can only take cases where rs is < than r/s because r/s may or may not be bigger than rs eg: if r=4 and s=1, rs<r/s; but if r=6 and s=2, rs>r/s Case 2: r is +ve and s is ve=> rs will always be greater than r+s => since this case does not satisfy the condition in Statement 2 (rs is the least number), we can disregard this case. Case 3: r is ve and s is ve=> Here too r+s will always be greater than rs => since this case does not satisfy the condition in Statement 2 (rs is the least number), we can disregard this case. Case 4: r is ve and s is +ve=> analysing the r+s, rs, rs and r/s no particular pattern is discernible. => so we can choose numbers to find cases where rs is the least but there are different answers for the max All in all, after looking at the cases, Case 2 and Case 3 can be disregarded and Case 1 and Case 4 does not give you a constant maximum. During the test, If you start with Case 1, given that case 1 does not give you a number which will always be maximum, you can strike Statement 2 as insufficient
