### HideShow timer Statistics

A certain salesman's yearly income is determined by a base salary plus a commission on the sales he makes during the year. Was the salesman's commission larger than his base salary last year?

(1) If the amount of the commission had been 30 percent higher, the salesman's total income (salary plus commission) would have been 10 percent higher last year.

(2) The absolute difference between the amount of the salesman's base salary and the amount of the commission was equal to 50 percent of the salesman's base salary last year.

Another simple question if 50/100 = 1/2
50/100 = .5

The absolute difference of two real numbers x, y is given by |x − y|, the absolute value of their difference.

Statement 2
The difference may be positive or negative... you don't know what.
Eliminate B &D

Statement 1
1 is sufficient
Hence A

Yes you can use both... use what you're more comfortable with more- fraction or decimal. Yes, you can ignore the zero

Statement 1
GMATD11 are you familiar with weighted averages?
You can evaluate this statement by using that concept.
1 is sufficient
Hence A

Yes you can use both... use what you're more comfortable with more- fraction or decimal. Yes, you can ignore the zero

Can you explain your approach in detail for lesser mortals like me

sorry my bad, simple equations will do

S+1.3C=1.1(S+C);
which simplifies to:
S=2C
Since both S, and C are positive;
S>C.
Sufficient.
