Question

Quizplus · Accepted Answer

The question involves performing arithmetic operations on the given numbers. The only operation available is addition as there are no parentheses or multiplication or division signs present. To add two numbers, their corresponding digits have to be added. However, since the letters can represent any real number, it is not possible to determine the exact values of the letters. So, the best approach is to choose the option that changes only one letter/number at a time. In this case, changing the third last digit from "9" to "a" in the third set of letters is the only viable option. This results in a change of 1 in the sum of the corresponding digits. Therefore, the answer is A.
