Answer :
Write all numbers that are less than 60 and greater than 55:
56, 57, 58, 59.
Add the digits in these numbers:
1. 56 {5+6=11};
2. 57 {5+7=12};
3. 58 {5+8=13};
4. 59 {5+9=14}.
Answer: 58
Using trial by error evalution on the values which lies within the interval given, the number which satisfies the condition is 58.
Using trial by error method :
The numbers while lies in the interval 55 < X < 60 are ; 56, 57, 58 and 59
Taking the sum of the digits :
- 5 + 6 = 11
- 5 + 7 = 12
- 5 + 8 = 13
- 5 + 9 = 14
The only value whose digits sums up to 13 is 58.
Therefore, the number whicj lies within the interval and gives a sum of 13 is 58.
