Answer 2

Answer:

Sana age is 20 and Anna age is 50 years

Step-by-step explanation:

Let Anna age be x and Sana age be y

Five years ago

x-5 = (y-5)3

x - 5 = 3y - 15

x = 3y -10 — statement i

Ten years later

x+10 = ( y+10) 2

x+10 = 2y+20

x - 2y = 10 — statement ii

x = 3y - 10

3y -10 -2y = 10

y = 20

x = 3y -10 = 50
