Direction for questions (71 to 75) : Answer the questions based on the information given below :
A cauliflower cold storage was set up in the year 2005. Three types of fresh cauliflowers were put into the storage at
the end of the months of February; low quality, medium quality and high quality. Low quality cauliflower decay
exactly after two months of its cold storage, medium quality after three months and high quality after four months.
Decayed cauliflower are removed and fresh cauliflowers are added to the storage at the end of each month. The
following figures indicate the number of cauliflowers of the above three types mentioned as type 1, type 2 and type
3 present in the storage at the start of March, April, May, June and July. Also, it is known that 86 fresh cauliflowers
