(2 votes, average: 4.50 out of 5)Peculiar two digit number
There is a peculiar two digit number which is three times the sum of its digits.
Can you find the number?
Lets say the number is ab
ab = 3(a+b) We can also write it as 10a + b = 3*(a+b) 7a = 2b a/b = 2/7
As it is given that it is a two digit number, so it can only be 27.
