Answer:
Mother: 40 years old
Rakhi: 15 years old
Step-by-step explanation:
Solution :
Let present age of Rakhi = x years
Present age of Mother = 4x
5 years later
Age of Rakhi =x+5
Ag of Mother =4x+5
Given 4x+5=3(x+5)
4x−3x=15−5
⇒x=10
Mother's age =4x=40 years
Plug 10 in for x to find Rakhis age
OOOOH my favorite LONG DIVISION but anyways the answer is 164.4
