1. A two digit number ab is added to another number ba, which is obtained by reversing the digits then we get three digit number. Thus (a + b) equals to:
Required numbers = 64 + 46 = 110
Option D is correct
Solution:
When two two digit numbers are added and the resultant value is a three digit number. It means there must be a carry over (i.e. The sum of unit digits be greater than 9. Similarly, the sum of the tens digit is also greater than 9)Required numbers = 64 + 46 = 110
Option D is correct
