One third of a two digit number exceeds its one fourth by 7. What is the sum of digits of the number?

Options
1) 72
2) 84
3) 15
4) 12

• 1/3(10x+y) - 1/4(10x+y)=7
  [(10x+y)]/12=7
  10x+y=84

• X/3=x/4 +7
  =84
  By summing the two digits 8+4=12

• first let the number be x
  so x/3 - x/4 = 7
  x/12 = 7
  x=84
  number is 84 and sum of digits is 8 + 4 = 12

• 4. 12
  Let number be x.
  Then, x/3-x/4=7
  => x = 84
  Thus sum of digits of 84 is 12(8+4).
