Question

Sudha is twice as old as her brother. Three years ago , Sudha's age was three times of her brother's age. Find the age of Sudha.​

Answer 1

Answer:

40 years

Step-by-step explanation:

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.
