  1. 1.99 million
  2. 19.95 million
  3. 8.35 million
  4. 11.60 million
  5. 21.95 million

In 2010, 24% of 80 million are employed in the Tech sector= 24/100 x 80 = 19.2 million
In 2050, 29% of 135 million are employed in the Tech sector= 29/100 x 135 = 39.15 million
So, there are 39.15 – 19.2 = 19.95 million more people employed in the tech sector in 2050 than in 2010

  1. In 2030, for every five people expected to work in the healthcare sector, ________ people will work in the education sector.

Don’t waste time in calculations. Both Healthcare and education are 11% in 2030, so there will be an equal number of people working in each of those sectors.

  1. 33:29:26
  2. 26:29:33
  3. 4:5:6
  4. 26:32:35
  5. 1:4:9

In 2010, 33% of 80 million are employed in the Tech sector= 33/100 x 80 = 26.4 million
In 2030, 29% of 110 million are employed in the Tech sector= 28/100 x 110 = 31.9 million
In 2050, 26% of 135 million are employed in the Tech sector= 29/100 x 135 = 35.1 million

  3. 7 million
  4. 8 million
  5. 9 million

2050: Education (14%), Healthcare (10%) and Manufacturing (15%) employ 39% of 135 million = 39/100 x 135 = 52.65 Mn
2010: Services (33%) and Technology (24%) employ 57% of 80 million = 57/100 x 80 = 45.6 Mn
The total number of people employed in Education, Helathcare and Manufacturing in the year 2050 will
Exceed the total number of people employed in Services and Technology in 2010 by
52.65 – 45.6 = 7.05 Mn
