This is a very difficult way to ask qs Vishal. But heres some input from what i thought is right.

Question 1 : Not worth calculating in actual gmat, because its very lenghty, but i think the answer might be C. what is it, let me know.
After solving the two equations , subtract 2 from 1 and you will get s= 3r + 2, which is of the same form y= 3x+2 , hence we can say that the line contains the point (r,s).

Qs2 : I think it might be E. I am really scared myself of these kind of qs where its not specified whether m and z are integers or whether they are positive... hence its very difficult to check all the possibilities

Qs 3: You have pasted the incomplete qs here, if its asked the range of positive numbers, then the answer would be 6 which is b but if its asked the range of the whole set then the answer might be 11 which is E

Qs 4 : This is very easy one. whats your doubt ? The prices of 3 items are 50, 20 and 20. The discouts are 10+2+2 so its 14 which is greater than 15 percent of 70 i.e 10.5 , The second part gives only price of one item, hence not sufficient. Only statement 1 is sufficient to solve the qs.

qs 5. This ones also simple. we have two equations from the qs stem.
0.1x +0.2y = 0.5z
x+y = z
Both statements give one value each, hence the equations can then be solved to find out the other two values. Hence each is alone sufficient to find teh answer.

Hope this helps.
Pls confirm if the earlier answers are correct ?
