Question 451291
Since the number is "divisible by 2 and 5", this means that the number is divisible by 10 (since 2*5 = 10). So the number ends with a 0. 



So the possible numbers are: 


100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 
200, 210, 220, 230, 240, 250, 260, 270, 280, 290



Now add up the digits of each possible number. The digits that add to 7 will give us the number. It turns out that 160 and 250 fit this description since 1+6+0=7 and 2+5+0=7



So the numbers are 160 and 250.
