Concept:Find remaining employees after given percentages of specific groups leave.Explanation:From the given data, number of males in B is $320$ and number of females in B is $450$.Similarly, number of males in D is $360$ and number of females in D is $490$.First, calculate employees leaving from B.$25\%$ of males from B leave: $25\% \text{ of } 320 = 80$ males leave.Remaining males in B: $320 - 80 = 240$.Females in B remain unchanged at $450$.Total remaining employees in B: $240 + 450 = 690$.Now, calculate employees leaving from D.$20\%$ of females from D leave: $20\% \text{ of } 490 = 98$ females leave.Remaining females in D: $490 - 98 = 392$.Males in D remain unchanged at $360$.Total remaining employees in D: $360 + 392 = 752$.Required ratio of remaining employees in B to D is $690 : 752$.Divide both terms by $2$ to get the simplified ratio.$690 \div 2 = 345$ and $752 \div 2 = 376$.Answer:The ratio is $345 : 376$, which matches option E.
