Let the present ages of Ram and Rehman be 8x and 9x. 
 
After 5 years, the ratio of their ages will be 9:10. 
 
begin mathsize 16px style fraction numerator 8 straight x space space plus space 5 over denominator 9 straight x space plus space 5 end fraction space equals space 9 over 10 end style
→ 10(8x + 5) = 9(9x + 5)
→ 80x + 50 = 81x + 45
→ x  = 5
 
Present age of Ram = 8x = 8 × 5 = 40 years
Present age of Rehman = 9x = 9 × 5 = 45 years
