Solution

The correct option is C 2.5
Let the daughter's present age be x and father's present age be 4x.
Then, 4x+5=3(x+5)
x=10
Hence, present age of daughter is 10 years and present age of father is 40 years.
So, after 5+5=10 years, daughter age would be 20 years and father’s age would be 50 years.
Hence, father would be 5020=2.5 times of daughter’s age.
