Explanation

Let the original family members be A, B, C, D (daughter). 5 years ago: sum was 94. Today (after 5 years): their sum would be 94 + 4×5 = 114. But daughter is replaced by daughter-in-law, and new sum is 92. Age difference = (sum with daughter) - (sum with daughter-in-law) = 114 - 92 = 22. This is the difference between daughter's age and daughter-in-law's age today.
