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.
