Question 767042: Find all the numbers between 125 and 325 which are divisible by 15 and the sum of whose digits is 9
Answer by ramkikk66(644)   (Show Source):
You can put this solution on YOUR website! Sum of digits is 9 implies that the number is divisible by 9.
So we are looking for numbers that are divisible by both 15 and 9.
Since LCM of 15 and 9 is 45, we need all the multiples of 45 in the range of
125 to 325.
The answer is - 135, 180, 225, 270, 315
