Sudha is twice as old as garima 10 years ago sudha was three times as old as garima find sudha's present age
Let Garima's age be x years
Sudha's age =2x
10 years ago,
Garima's age=x−10
Sudha's age=2x−10
According to the question,
2x−10=3(x−10)
⇒2x−10=3x−30
⇒3x−2x=30−10
∴x=20
∴ Garima's present age is 20years
Hence, sudha's present age is =2×20=40 years.
