Father = 7 * son
after 7 years,
(Father + 7 years ) = 5 * (Son + 7 years)
Father + 7 years = 5 * Son + 35 years
7 * Son + 7 years = 5 * Son + 35 years
2 * Son = 28 years
Age of Son = 14 years
Father's age = 7 * 14 = 98 years.
Hence, the sum of their ages = 112 years
after 7 years,
(Father + 7 years ) = 5 * (Son + 7 years)
Father + 7 years = 5 * Son + 35 years
7 * Son + 7 years = 5 * Son + 35 years
2 * Son = 28 years
Age of Son = 14 years
Father's age = 7 * 14 = 98 years.
Hence, the sum of their ages = 112 years
