A, b, c are non negitive integers such that 28a+30b+31c = 365. A) Greater than 14 b) less than or equal to 11 c) 13 d) 12 Solution: In a calender, Number of months having 28 days = 1 Number of months having 30 days = 4 Number of months having 31 days = 7 28 x 1 + 30 x 4 + 31 x 7 = 365 Here, a = 1, b = 4, c = 7.
