My vote is for A.

Statement 1:

difference between salaries is \$5. Pick numbers...30 and 35 + 6% increase yields a difference of \$5.30. You get the same exact value when you pick other numbers that are \$5 apart (i.e 42 and 37). So the dollar difference will always be \$5 (+change bue question asks about \$ difference)

Statement 2:
Not enough information. 4:3 ratio could mean that one person makes \$12 and the other makes \$9 or that one person makes \$40 and the other \$30. Difference in salary would vary widely then - not sufficient.

A sufficient.

Since both has no change in their salary number (ex 40 and 45) and percentage increase also the same, the new salary revised would be the same difference. So A stands.

Interesting observation. Tried the same with \$100 and \$105 and it also came out to a \$5.30 difference.

(A)

We do not need any examples here.........
Initially J-M = 5
Now it will be 106%(J)- 106%(M)
ie 106%(J-M) = 106% (5) = 5.3\$
So A
