Question

10 years ago, Chandravati's mother was four times older than her daughter. After 10 years, the mother will be twice older then the daughter. The present age of Chandravati is?

Answer 1

Let the age of daughter be x.
The age of Chandravati's mother be 4x.
10 years ago,
The age of Chandravati's mother = 4x-10

After 10 years , the mother will be twice older than the daughter
4x-10+10=4x
2(x+10)

4x=2(x+10)
4x=2x+20
4x-2x=20
2x=20
x=20/2
x=10

The age of Chandravati is 10 years

I don't know the answer is correct but I just tried because I am new so...
