Sumit stays in Noida in a joint family comprising of his parents, uncle, aunt, an elder sister and a
cousin two years younger than him. Sumit completed his MBA in 2013, from a reputed B-School.
That year, the average age of Sumit's family was 41. Sumit got married in 2015 and two years after he
became father. If the average age of Sumit's family in 2019 remains same as in 2013, and Sumit is
older than his wife by 3 years, at what age did Sumit graduate MBA ?
