ANSWER :
15, 20
Step-by-step explanation:
Let the age of reena be 3x and tina be 4x because the ratio is 3 : 4
5 years ago
Age of Reena = 3x - 5
Age of Tina = 4x - 5
Ratio = 2 : 3
Therefore,
(3x-5)/(4x-5) = 2/3
3(3x - 5) = 2( 4x - 5)
= 9x - 15 = 8x - 10
= 9x - 8x = 15 - 10
= x = 5
Present age of Reena = 3x = 3(5) = 15
Present age of Tina = 4x = 4(5) = 20
