Step-by-step explanation:

  • Given that,
  • Ratio of reena and tine age = 3:4
  • So, Let the present age of reena and tina be 3x and 4x .
  • Five years ago their age = 2:3
  • Now, their age = 3x - 5 and 4x - 5
  • According to the question,
  • 3x - 5/4x - 5 = 2/3
  • 3( 3x-5 ) = 2 (4x -5) { Cross multiplication }
  • 9x-15 = 8x - 10
  • 9x-8x = -10+15
  • x = 5
  • So, the present age of reena = 3x = 3*5 = 15 years & present age of tina = 4x = 4*5 = 20 years.
