Question

Convert a special palindrome number using 139.
( 3 marks )

Answer 1

Solution:
The given number is 139.
Turn it back to front = 931 (0.5 marks)
Add both of them ​ = 139+931 = 1070 (0.5 marks)
It is not a palindrome number.​ (0.5 marks)
So we will repeat the above steps to get a palindrome number.​ (0.5 marks)
Turning 1070 back to front, we will get 0701 (0.5 marks)
Add both of them = 1070+0701 = 1771.
Hence, 1771 is a palindrome number. (0.5 marks)
