Answer:
Ravi is 10 years old and Ravi's father is 40 years old.
Step-by-step explanation:
If f is father's age and r is Ravi's age,
f = 4r (and) f + 5 = 3(r + 5)
f + 5 = 3r + 15
f = 3r + 15 - 5
= f = 3r + 10
As f = 3r + 10 and f = 4r,
3r + 10 = 4r
3r + 10 - 3r = 4r - 3r
r = 10
As f = 4r,
f = 4 * 10 = f = 40
