I’m pretty sure you meant 20-17 but three.
Answer:
Jennifer age = 20.
Step-by-step explanation:
Given : Jennifer is now 3 years older than Peter. If, in 12 years, the sum of their ages will be 61.
To find : how old is Jennifer now.
Solution : We have given
Let the age of Peter = x .
According to question
Jennifer is now 3 years older than Peter.
Jennifer age = x + 3
After 12 year
Peter age = x + 12
Jennifer age = x + 15
Sum of their age would be 61.
x +12 + x +15 = 61.
2x + 27 = 61 .
2x = 61 - 27.
2x= 34.
On dividing both sides by 2
x = 17
Peter age = 17.
Jennifer age = 20.
Therefore, Jennifer age = 20.
