If the number consist of three digits whose sum is 10.The middle digit is equal to the sum of other two.The number increases by 99 if its digits are reversed.What is the number?

• 253 is the number.
  
  Sum of Digits = 2+5+3 = 10
  Middle digit = First Digit + Last digit ==> 5 = 2 + 3
  
  Reverse of number = 352
  Original Number = 253
  
  Number increase by 99, when its reversed : 253+99 = 352. Proved

• ans=253
  given x+y+z=10
  according to question y=x+z
  then x+(x+z)+z=10
  x+z=5
  the following point satisfied the equation (0,5) (5,0) (1,4) (4,1) (2,3)(3,2)
  in which only(2,3) satisfied the question so y=2+3=5
  no=253 and reverse the no we get 352 which is 99 more than 253.
