Answer:
Hmm
Step-by-step explanation:
Let the age of rakhi =x years
And according to the question it is given that mother age is four times the age of rakhi.
So the age of rakhi’s mother =4x years.
After 5 years
Age of rakhi =x+5 years
Age of mother =4x+5 years.
Now according to the second condition of question after five years. Her mother will be three times as old as rakhi.
⇒4x+5=3(x+5)
⇒4x+5=3x+15
⇒4x−3x=15−5
∴x=10
Hence the present age of rakhi = x years =10 years and
the age of Rakhi’s mother= 4x years = 4×10=40years

Step-by-step explanation:
rakhi age : y
rakhi mother age = 4y
equation formed according to question
(y+5)×3=4y+5
3y+15=4y+5
15-5=4y-3y
10=y
hence rakhi age = 10
mother age = 10x4=40
