The given bar graph shows the number of students enrolled in Institutes A and B during 5 years (2018 to 2022). What is the ratio of the total students enrolled in Institute B in 2019, 2020, and 2022 to that of the total students enrolled in Institute A in 2018, 2020, and 2021?
37 : 28
Given:
Students enrolled in Institute B in 2019 = 350
Students enrolled in Institute B in 2020 = 375
Students enrolled in Institute B in 2022 = 200
Total students enrolled in Institute A in 2018 = 150
Total students enrolled in Institute A in 2020 = 300
Total students enrolled in Institute A in 2021 = 250
Formula used:
Ratio = Total students in Institute B (2019, 2020, 2022) / Total students in Institute A (2018, 2020, 2021)
Calculations:
Total students in Institute B (2019, 2020, 2022) = 350 + 375 + 200 = 925
Total students in Institute A (2018, 2020, 2021) = 150 + 300 + 250 = 700
⇒ Ratio = 925 / 700
⇒ Ratio = 37 / 28
∴ The correct answer is 37 : 28.
