Question

A three digit is such that his number itself is divisible by sum of its digits. The sum of 100 digit is 6 while the sumnof tens and unit digit is 5. What is the ratio of unit and tens digit?

Answer 1

Answer:

H+U=6

T+U=5 (where H is hundren, T is ten and u is unit)

Therefore, H-T=1 (FROM THIS WE KNOW THAT H IS GRRATER THAN T)

Since H+U=6, H Cannot be greater than 6

Since this is 3 digit number H cannot be 0

The value of T IS H-1

SO by substitute the value of H from 1 to 6 until the given condition is satisfied.

Therefore the number is 432

The ratio of U and T is 2:3
