Answer:

  • Sara is 10 and Laila is 8

Step-by-step explanation:

  • Sara's age = s
  • Laila's age = l

The ratios:

  • s/l = 5/4 ⇒ s = 5l/4
  • (s + 2)/(l + 2) = 6/5 ⇒ 5(s + 2) = 6(l + 2) ⇒ 5s = 6l + 2

Substitute s into the second equation and solve for l:

  • 5(5l/4) = 6l + 2
  • 25l = 24l + 8
  • l = 8

Fins s:

  • s = 5*8/4 = 10
