U almost got the correct solution... but fell into the classic
2 eqn 2 variable trap.

Stmt 1: j + k = 50k

insufficient.


stmt 2:
in 1985, each of their salaries were 10% more than their
corresponding prev yr salaries.

so
1.1j + 1.1k = 55k
=> 1.1(j+k) = 55k
=> j +k = 50k

insufficient.


combining them.
Both equations are identical.
hence no unique solutions.

therefore E

Here is the takeaway from this (from one of Ron/Stuart's comments)

The real "rule" in mathematics is this: If you have n *independent* *linear* equations and n unknowns, you can solve for all n of your unknowns. By "independent", we mean that you can't derive any one equation from the others.

yup, gotta watch out for those!

Damn !! laziness ! do cost crazy !!

thanks guys
