Given:
Consider the total age of 5 children with age difference 3 years is 50 years.
To find:
The age of the youngest and oldest child.
Solution:
Let the ages of the 5 children are x-6, x-3, x, x+3, x+6.
Sum of their ages is 50 years.
![(x-6)+(x-3)+x+(x+3)+(x+6)=50](https://img.qammunity.org/2022/formulas/mathematics/college/ci34unp35w0f9em9nk0nwfzbloibx897k7.png)
![5x=50](https://img.qammunity.org/2022/formulas/mathematics/high-school/o7o3hc3qbx8qee83ue0fazc50epkwizft7.png)
![x=(50)/(5)](https://img.qammunity.org/2022/formulas/mathematics/college/ybem595y8e1zugs3unpe1sd4s2wxjf0s1a.png)
![x=10](https://img.qammunity.org/2022/formulas/mathematics/high-school/73ltnq8a3crfk111hyc6lpiuufywuosb.png)
The age of the youngest child is
![10-6=4](https://img.qammunity.org/2022/formulas/mathematics/college/4flj8ub00bu5agfa0v7hep2raxn0f0vjlp.png)
The age of the oldest child is
![10+6=16](https://img.qammunity.org/2022/formulas/mathematics/college/m13v37py8garo7q06bxhm2mtgz9106peh9.png)
Therefore, the age of youngest child is 4 years and the age of the oldest child is 16 years.
