Step-by-step explanation:
Here's the correct question:
The total ages of 5 children born at the intervals of 3 years each is 50 years. Find the age of the youngest and the oldest child.
From the information given, we can then make the following assumption with regards to their ages.
First child = y
Second child = y + 3.
Third child = y + 6
Fourth child = y + 9
Fifth child = y + 12
Therefore, y + y+3 + y+6 + y+9 + y+12 = 50
5y + 30 = 50
5y = 50 - 30
5y = 20
y = 20/5
y = 4
Youngest child = 4 years
Oldest child = y + 12 = 4 + 12 = 16 years
