28a+30b+31c=365 then find a+b+c?

• 12
  a,b & c are nothing but the months of 28 days,30 days & 31 days in a year
  28(1)+30(4)+31(7)=28+120+217=365
  So a+b+c=1+4+7=12

• 28,30,31 are months in year
  in there are 12 months
  jan,feb,march,april,may,june,july,aug,spect,oct,nov,dec
  in a year there 1month containing 28days
  in a year there 4months containing 30days
  in ayear there 7months containing 31days
  so that 1+4+7=12 i.e a+b+c=12

• 31*5 can make the last digit as 5 of 365. Therefore we got 165 now more 200 can be made by multiplying something that generates 0's at the unit place. Therefore 28*5 and 30*2 will do the rest. The sum of a+b+c generated is 5+2+5 = 12.

• ans is 12
  represents month in a year
  a - 28 1(feb consist of 28 days)
  b - 30 4(apr,jun,sep,nov consist of 30 days)
  c - 31 7(jan,mar,may,jul,aug,oct,dec has 31 day )
