Hey fibbonnaci,
how is the present perfect tense maintained in option D ?

Here the verb is 'have unearthed' - present perfect. So we maintain this tense unless a change is required.

karan, I did the same thing. though can u explain it with #s? I'm guessing that would make it quicker and simpler. It is a good idea to draw a number line: two cases are possible: a..........b.........0 or a.........0........b (I) this one talks about a.........0........b but what about a..........b...

What is the value of w+x+y+z?
Each of the numbers w,x,y and z is equal to either 0 or 1. What is the value of w+x+y+z?
(1) w/2+x/4+y/8+z/16=11/16
(2) w/3+x/9+y/27+z/81=31/81
Different and quicker approaches if this had been a PS sum?

If its rising from the 3rd quadrant(being a +ve slope), the positive x intercept would be in the first quadrant.......
