Answer 2

Answer:

20 Years

Step-by-step explanation:

Let say   Tina  age  =   9T  Years

then Rakesh age  = 10T    Years

10 Yaar ago Tina age  = 9T - 10

10 Year ago Rakesh age  = 10T - 10 = 10(T-1)

(9T - 10)/ (10(T-1) )  = 4/5

=> (9T - 10)/ (2(T-1) )  = 4

=> 9T - 10  = 8(T - 1)

=> 9T - 10 = 8T - 8

=> T = 2

Present Age of Rakesh = 10T  = 20 Years
