A survey employers found that during 1993 employment costs rose 3.5 percent, where employment costs consist of salary costs and fringe-benefit costs. If salary costs rose 3 percent and fringe-benefit costs rose 5.5 percent during 1993, then fringe-benefit costs represented what percent of employment costs at the beginning of 1993?
A. 16.5%
B. 20%
C. 35%
D. 55%
E. 65%
The OA is B.
I solve this PS questions of the following way,
$$s\left(1.03\right)+f\left(1.055\right)=sf\left(1.035\right)$$
$$sf=\frac{0.02}{0.005}=4$$
$$\frac{f}{s+f}=\frac{1}{5}=20\%$$
Is there another approach to solve this PS question? Can any experts help, please? Thanks!
