Rita was studying in class 9th C of St. Surya Public School, Mohali, New Delhi-110030. Once Ranjeet and his daughter Rita were returning after attending teachers' parent meeting at Rita's school. As the home of Ranjeet was close to the school so they were coming by walking. Rita asked her father, "Daddy how old are you?" Ranjeet said, "At present, sum of ages of both of us is 55 years and after 10 years my age will be double of you."
