What is the four-digit number in which the first digit is 1/3 of the second,the third is the sum of the first and second, and the last is three times the second?

• The 4 digit number is 1349.
  It is given that the first digit is 1/3 of the second. There are 3 such possibilities 1)1 and 3
  2)2 and 6
  3)3 and 9
  Now, the third digit is the sum of the first and second digits.
  1)1 + 3 = 4
  2)2 + 6 = 8
  3)3 + 9 = 12
  It is clear that option 3 is not possible. So we are left with only two options.Also, the last digit is three times the second, which rules out the secondoption. Hence, the answer is 1349
