Answer:

  • Sihle is 40 and Zinhle is 20

-----------------------

Let the current ages be x and y.

As per given information we can set up two equations:

  • 1) x = 2y, Sihle is now twice as old as her daughter Zinhle
  • 2) x - 10 = 3(y - 10), 10 years ago she was 3 times older

Substitute 2y for x into second equation and solve for y:

  • 2y - 10 = 3y - 30
  • 3y - 2y = 30 - 10
  • y = 20

Find the value of x:

  • x = 2*20 = 40
