Ishu purchased his bungalow how many years after Deepa?

Study the following information carefully and answer the question given below: Eight friends – Amit, Babli, Chand, Deepa, Ishu, Farun, Gori and Hemant purchased bungalows on same date of different years viz. 1988, 1993, 1995, 1996, 2000, 2001, 2006 and 2009 but not necessarily in same order. They all have purchased their bungalows on 1st of June of their respective years. (Note- For calculation of time period, please consider 1st June 2018 as cut-off date.) Babli purchased his bungalow immediately before Deepa. Only one person purchased his bungalow between Deepa and Ishu, who purchased in a leap year. Two people purchased bungalow between Farun and Gori who purchased it 12 years ago. Amit was neither the first nor the last person to buy a bungalow.
