Answer:
- Present age of Ram = 40 yrs
- Present age of Rehman = 45 yrs
Explanation:
Given that,
Ratio of present ages of Ram and Rehman is 8 : 9
so, Let their present ages be 8 x and 9 x
Now,
As given that
after 5 years ratio of their ages will become 9 : 10
so,
Age of Ram after 5 yrs = 8 x + 5
and, Age of Rehman after 5 yrs = 9 x + 5
Hence,
→ ( 8 x + 5 ) / ( 9 x + 5 ) = 9 / 10
cross multiplying
→ 80 x + 50 = 81 x + 45
→ 50 - 45 = 81 x - 80 x
→ x = 5
So,
- Present age of Ram = 8 x = 8 ( 5 ) = 40 yrs
and
- Present age of Rehman = 9 x = 9 ( 5 ) = 45 yrs.
