Step-by-step explanation:

Consider the provided information.

Five years ago, the average age of Rimi’s age that time and Ruhi’s age that time = 12 years

That means their total age is:  

12 = Sum of Rimi and Ruhi's age / 2

Sum of Rimi and Ruhi's age = 24

Three years from now, that means after 5+3=8 years the  respective ratio between Rimi's  age and Ruhi's age that time  will be 5 : 3.

Sum of their age after 8 years = 24 + 16 = 40

Rimi’s age after 8 years =  40 * 5/8 = 25

Rimi’s present age = 25 – 3 = 22.

Hence, the present age of Rimi is 22 years.
