Question

Sandhya is 6 years older than 3 times of her daughter Pinky. If Pinky is 13 years now, what was the age of Sandhya at the time of birth of Pinky?​

Answer 1

Answer:

Let present age of daughter be x.

So 5 years ago her age =x−5

Her mother's age is 7(x−5)

Including 5 years from past to present and then to future =10

So 7x−35+10=3(x−5+10)

7x−25=3x+15

4x=40

x=10

so daughters age=10

mother's age=4×10=40.
