Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFGiven:
Professors added in 2019 = 100
Professors added in 2020 = 150
Professors added in 2021 = 180
Professors added in 2022 = 200
Associate Professors added in 2019 = 110
Associate Professors added in 2020 = 140
Associate Professors added in 2021 = 190
Associate Professors added in 2022 = 220
Formula used:
Difference = Total professors added - Total associate professors added
Calculations:
Professors added from 2019 to 2022:
⇒ 100 + 150 + 180 + 200 = 630
Associate professors added from 2019 to 2022:
⇒ 110 + 140 + 190 + 220 = 660
Difference:
⇒ 630 - 660 = -30
∴ The correct answer is option (1).
