35 - some number = 15 and usually you are required to find the number.
Any number when doubled becomes even. Thus the key part of the question is identifying a 3 digit even number that you can add 2 to to become a 4 digit number. The answer is 998. Thus to find the original number we need to do 998/2. This calculates to 499.
