Project ForgeA firm hires employees at five different skill levels P, Q, R, S, T. The shares of employment at these skill levels of total employment in 2010, from a pie chart, are: P=20%, Q=25%, R=25%, S=25%, T=5%. There were a total of 600 employees in 2010 and the total employment increased by 15% from 2010 to 2016. The total employment at skill levels P, Q and R remained unchanged during this period. If the employment at skill level S increased by 40% from 2010 to 2016, how many employees were there at skill level T in 2016?
- A30
- B35
- 60
- D72
Explanation
2010 counts: P=120, Q=150, R=150, S=150, T=30 (out of 600 total). 2016 total = 600 x 1.15 = 690. P+Q+R stays fixed at 120+150+150=420. S grows 40%: 150 x 1.4 = 210. So T in 2016 = 690 - 420 - 210 = 60.
