Let the number of male employees in 2023 and female employees in 2022 is 8n and 3n respectively.
Number of female employees in 2023 = 8n - 15
Total number of female employees in 2022 and 2023 together = 40
3n + 8n - 15 = 40
11n = 55
n = 5
Total number of male and female employees, who join the company in 2022 and 2023 together = 100
Number of male employees in 2022 = 100 - 8*5 - 40 = 20
In tabular form -
| Employees | 2022 | 2023 |
| Male | 20 | 40 |
| Female | 15 | 25 |
Number of male and female employees together in 2022 = 20 + 15 = 35
Number of male and female employees together in 2023 = 40 + 25 = 65
Required difference = 65 - 35 = 30
