5 should be changed

The required number to obtain the desired result is 50. so by adding 50 to 913 to get a result of 2456 is 963.

the que is wrong ..istead of 913 there should be 973.so the largest digit to be changed will be 7.
ques says what is the largest digit on 10th place to be changed,,

The answer is 4 because 4+5+1=10. 5 should be present instead of 0. Hence, to make it 5 we need to change the greatest digit possible. We cannot change 5 to 10 to get required value. Hence we change next greatest digit 4 to 9 to get desired value that is we add 5 to 4 to get 5.
9+5+1=15
