(5) 42 years; 32 years​

Answer 1

Answer:

4)54years,36years

Step-by-step explanation:

Age ratio 12 years from now 11:5

Age difference: x6. If ad = x6 father and daughter’s ages = x6

Father age 11 X 6 = 6; Daughter age: 5 X 6 = 30; Age difference: 6 X 6 = 36

The father will be 66 years old and his daughter will be 30 years old (11:5) in 12 years.

hence, Presently father is 54 and daughter is 18 (3:1).

and father was 36 years old when daughter was born...
