this is the correct answer

Answer 2

Answer:

35 yrs and 25 yrs

Step-by-step explanation:

Let age of two sisters be x and y,

x−y=10 (1)

x−15=20 (2)

x−15=2(y−15) (3)

Substituting (2) in (3)

20=2y−30

50=2y

y=25 (4)

Substituting (4) in (1)

x−25=10

x=35

Their present ages are 35 years and 25 years.
