The digits of positive integer, having three digit , are in AP and the...
Let a - d, a, a + d be the three digits of a three digit number respectively at unit place, ten's place, hundreth place.
∴ The number = 100 (a + d) + 10 + a + a - d
Since the sum of digits is 15
∴ a -d + a + a + d = 15 or 3a = 15 or a = 5
The number obtained by reversing the digits = 100 (a - d) + 10a + (a + d) ...(ii)
According to the given condition
100 (a - d) + 10 a + a + d = 100 (a + d) + 10a + a - d - 594
or 100a - 100d + 10a + a + d = 100a + 100d + 10a + a - d - 594
or 198d = 594 or d = 3
∴ Original number = 100 (5 + 3) + 10 (5) + 5 - 3 = 800 + 50 + 2 = 852
Verification: On reversing the digits, the number is 258
852 - 258 = 594

The digits of positive integer, having three digit , are in AP and the...
Given information:
- The digits of a positive integer, with three digits, are in an arithmetic progression (AP).
- The sum of the digits is 15.
- The number obtained by reversing the digits is 594 less than the original number.
Let's solve the problem step by step:
Step 1: Understanding the arithmetic progression
- Let's assume the three digits of the number to be a-d, a, and a+d.
- The sum of these digits would be (a-d) + a + (a+d) = 3a, which is given to be 15.
- So, 3a = 15, or a = 15/3 = 5.
Step 2: Forming the number with the digits
- The number with digits a-d, a, and a+d can be represented as (a-d)*100 + a*10 + (a+d).
- Substituting the value of a as 5, we get the number as (5-d)*100 + 5*10 + (5+d).
Step 3: Reversing the digits and forming the second number
- Reversing the digits gives us a new number with digits (a+d), a, and (a-d).
- This number can be represented as (a+d)*100 + a*10 + (a-d).
- Substituting the value of a as 5, we get the reversed number as (5+d)*100 + 5*10 + (5-d).
Step 4: Finding the relationship between the numbers
- The problem states that the reversed number is 594 less than the original number.
- Mathematically, we can write this as:
(5+d)*100 + 5*10 + (5-d) = (5-d)*100 + 5*10 + (5+d) - 594.
Step 5: Solving for the value of d
- Simplifying the equation from step 4, we get:
600 + 50d - 50 = 500 - 50d + 594.
- Combining like terms, we have:
100d - 50d = 500 + 594 - 600 + 50.
50d = 544.
d = 544/50 = 10.88.
- Since d needs to be an integer, we can conclude that there is no solution to the problem.
Conclusion:
- There is no three-digit number that satisfies the given conditions.
- The digits of a positive integer, with three digits, are in an arithmetic progression (AP).
- The sum of the digits is 15.
- The number obtained by reversing the digits is 594 less than the original number.
