The following table presents the details about the number of software development projects handled by two software companies A and B over five years from 2016 to 2020. Both the companies are engaged in handling both Government Projects (GPs) as well as Non-Governmental Projects (NGPs). Based on the data in the table, answer the question that follows.
Year-wise handling of Projects
Year | Software Company A | Software Company B |
|---|---|---|
2016 | 180 | 130 |
2017 | 230 | 320 |
2018 | 360 | 210 |
2019 | 250 | 190 |
2020 | 300 | 350 |

Show answer & explanation
Correct answer: B
CONCEPT
A percentage represents a part out of 100. To find p% of a quantity Q, compute (p/100) × Q.
When a part M is removed from a total L, the remainder is L − M; equivalently, it is (100% − p%) of L.
APPLICATION
From the table, company A handled 360 projects in 2018 and 250 projects in 2019, so L = 360 + 250 = 610.
The number of government projects is M = 20% of 610 = (20/100) × 610 = 122.
Substituting these values gives L − M = 610 − 122.
CROSS-CHECK
Keeping 80% of L gives (80/100) × 610 = 488, which agrees with the subtraction.
RESULT
Therefore, L − M = 488.
