original no. is 49 there is a trick to solve these types of sums
firstly note all the 2 digit numbers whose sum is 13
then interchange them
49 94
58 85
67 76
76 67
85 58
94 49
then subtract all the no.
if we subtract 49 from 94 we will get 45
then they are saying that the number is 45 more than the original number . it means that the original number is less than new number so the original no is 49
