If a girl is 5 years old and her father is 31 years old now then in how many years the father be 3 times old as his daughter

Because the father is 26 years older than the daughter, the father will be three times the daughter’s age when she is 13 years old. When she is 13 years old, the father will be 39 years old. 13 • 3 = 39.
