Sum of nos. not divisible by 6 and below 400 = {sum of all nos. below 400} - {sum of all nos. divisible by 6 and below 400} = {1+2+........+399} - {6+12+18+..........+396} = {399/2[1+399]} - {66/2[6+396]} = {399*200} - {33*402} = {79800}-{13226} = 66574 you can solve this and will get the answer.
Sum of nos. not divisible by 6 and below 400 = {sum of all nos. below 400} - {sum of all nos. divisible by 6 and below 400}
= {1+2+........+399} - {6+12+18+..........+396}
= {399/2[1+399]} - {66/2[6+396]}
= {399*200} - {33*402}
= {79800}-{13226}
= 66574
you can solve this and will get the answer.
