#Problem1 (Multiples of 3 and 5) If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.

Find the sum of all the multiples of 3 or 5 below 1000.

#Solution1 (Python3) sum=0 for i in range(1,1000): if((i%3==0)||(i%5==0)): sum=sum+i print(sum)

Problem2 (Even Fibonacci) Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:

1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...

By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.

Solution2 (Python3) f=1 s=2 t=f+s while(t!=4000000): if(t%2==0): print(t) t=f+s f=s s=t
