The table shows the number of software development projects handled by companies A and B from 2016 to 2020 (Government and Non-Government projects combined).
| Year | Company A | Company B |
|---|---|---|
| 2016 | 180 | 130 |
| 2017 | 230 | 320 |
| 2018 | 360 | 210 |
| 2019 | 250 | 190 |
| 2020 | 300 | 350 |
If L represents the total number of projects handled by Company A in 2018 and 2019 together, and M represents 20 percent of L as the number of GPs, then L minus M is
A454
B488 ✓ Correct
C478
D466
Correct answer: (B) 488
Explanation
L minus M is 488, so the answer is 488.
Company A handled 360 projects in 2018 and 250 in 2019.
So L, the total for the two years, is 360 plus 250, which is 610.
M is 20 percent of L, which is 610 times 20 over 100.
So M is 122.
L minus M is 610 minus 122.
That equals 488.
