Answer 2

If the sum of three digit number and the number obtained by reversing the order of the digit is 1232, then the tenths digit of the number is 1.

• Let the three digit number be xyz.
• Therefore, on reversing the order of the digits, the number will be zyx.
• It is given in the question that xyz + zyx = 1232.
• Hence, we can infer that z+x = 2, 2y = 3 and x+z = 12.
• But, it is not possible to have different values of x+z.
• Therefore, x+z  is actually equal to 12 and the 1 gets carry over.

            ⇒ 1 + 2y = 3

            ⇒ y = 1

Therefore, the tenths digit is equal to 1.
