Answer:

Age of sister = 20

Age of uncle = 40

Step-by-step explanation:

Let the age of sister is = x

Let the age of uncle is = 2x

Before 10 years

Age of sister is = x-10

Age of uncle is = 2x-10 or 3(x-10)

Now, 2x-10 = 3(x-10)

2x-10 = 3x-30

By shifting

30-10 = 3x-2x

x = 20

By putting the value of x

Age of sister is 20

Age of uncle is = 2x =2×20 = 40
