==> On the straight line, the greatest absolute value is |a+b|=|-1.8+(-1.3)|=3.1.

Therefore, the answer is A.

Answer: A

So basically we should take proximity distance given in the line as true ? :) .

*Edit : Even if we take doesn't c + 2 max value = 99999 + 0.5 or 2.9 + 0.9 ? which is greatest. than a + b whose maximum value is 1.999 + 0.999 = 3 ? figure is confusing a bit.

Which absolute value of the following is the greatest?

A. a+b
B. b+d
C. c+e
D. c+d
E. b+e


well!!
for me , figure is quiet confusing...

can any one help!!


That is the reason why Q is 700+.
In normal scenario with correct figure, this would be just 600 level.

Even if you figure out Correct figure, why C is not better than A????

HI Chetan!!!
well, i thought of the solution in terms of distance theory of the modulas...mod(a+b) is the distance of a from -b...that ways....b which is less than zero automatically goes further from a as compared to distance calculated for any other option....although i did not make precise calculation.
Hope I was thinking on correct lines....

MUST ADMIT FIGURE IS SUPER CONFUSING...and that helped in NOT making precise calucations:)
