(a) What is the percentage increase in the income of the CEO A in 2017 as compared to 2022?
(b) What is the ratio of income of the CEOs A, B, and C in 2020?
(c) Find the sum of the salaries received by all three CEOS in each year. In which year, the sum of the salary of all three CEO’s?
(d) The total expenditure of the CEO A in 2019 was Rs 2.5 lakhs, which was increased by 50% in the year 2020. Find the percentage of savings in the year 2020 with respect to Income earned by the CEO A in the year 2020.
(e) Find the difference between Income of the CEO A and CEO B in the years 2018, 2019 and 2020 taken together to the Income of CEO B and CEO C in the years 2020, 2021, 2022.
The income of the CEO A in 2017 = 1.5 lakhs
The income of the CEO A in 2022 = 4.5 lakhs
Increase in the income of the CEO A = 4.5 – 1.5 = 3 lakhs
Hence, the percentage increase in the income of the CEO A in 2017 as compared to 2022,
= 3/1.5 × 100 = 200%
(b) What is the ratio of income of the CEOs A, B, and C in 2020?
Answer:
IN 2020,
Income of the CEO A = 4 lakhs
Income of the CEO B = 4 lakhs
Income of the CEO C = 4.5 lakhs
Hence, the ratio of income of the CEOs A, B, and C in 2020 = 4:4:4.5 = 8:8:9
(c) Find the sum of the salaries received by all three CEOs in each year. In which year, the sum of the salary of all three CEO’s?
Answer:
Sum of the salaries of all the three CEOs in 2017 = 1.5 + 1 + 2 = 4.5 lakhs
Sum of the salaries of all the three CEOs in 2018 = 2 + 2.5 + 3 = 7.5 lakhs
Sum of the salaries of all the three CEOs in 2019 = 3 + 2.5 + 3.5 = 9 lakhs
Sum of the salaries of all the three CEOs in 2020 = 4 + 4 + 4.5 = 12.5 lakhs
Sum of the salaries of all the three CEOs in 2021 = 4 + 4.5 + 4.5 = 13 lakhs
Sum of the salaries of all the three CEOs in 2022 = 4.5 + 4.5 + 5 = 14 lakhs
Hence, the sum of the salary of all three CEOs is higher in 2022 and lower in 2017.
(d) The total expenditure of the CEO A in 2019 was Rs 2.5 lakhs, which was increased by 50% in the year 2020. Find the percentage of saving in the year 2020 with respect to Income earned by the CEO A in the year 2020.
Answer:
The total expenditure of the CEO A in 2019 = Rs 2.5 lakhs
Expenditure of the CEO A is increased by 50% in 2020,
= 2.5 lakhs + 50/100 × 2.5 lakhs
= 3.75 lakhs
Income of the CEO A in the years 2020 = 4 lakhs
Expenditure of the CEO A in 2020 = 3.75 lakhs
Hence, the percentage of savings in the year 2020 with respect to Income earned by the CEO A in the year 2020 = (4 – 3.75)/4 × 100 = 6.25%.
(e) Find the difference between Income of the CEO A and CEO B in the years 2018, 2019 and 2020 taken together with the Income of CEO B and CEO C in the years 2020, 2021, 2022.
Answer:
Income of the CEO A in the years 2018, 2019 and 2020 = 2 + 3 + 4 = 9 lakhs
Income of the CEO B in the years 2018, 2019 and 2020 = 2.5 + 2.5 + 4 = 9 lakhs
Income of the CEO A and CEO B in the years 2018,2019 and 2020 = 9 + 9 = 18 lakhs
Income of CEO B in the years 2020, 2021, 2022 = 4 + 4.5 + 4.5 = 13 lakhs
Income of CEO C in the years 2020, 2021, 2022 = 4.5 + 4.5 + 5 = 14 lakhs
Income of CEO B and CEO C in the years 2020, 2021, 2022 = 13 + 14 = 27 lakhs
Hence, the difference between Income of the CEO A and CEO B in the years 2018,2019 and 2020 taken together to the Income of CEO B and CEO C in the years 2020, 2021, 2022,
= (18 – 27) lakhs
= – 9 lakhs.
