In a Calendar format a, b, c are non negative integers such that…

Normally, if we take a look at the calendar, we have 12 months and sum up all the days we get 365, ( except for the leap year )

28a + 30b + 31c = 365

In the calendar, we have months with 28 days, 30 days , 31 days, a, b, c represent the number of months consisting the date

So, in a normal year, we have one month which has 28 days

So, a = 1

We have 4 months having 30 days ( April , June , September , November )

So, b = 4

We have 7 months which have 31 days ( January, March, May, July, August, October and December )

So, c = 7

a , b , c are non-negative

a + b + c = ?

1 + 4 + 7 = ?

a + b + c = 12
