law?

b) 11 years
c) 25 years
d) 19 years

Answer 1

Answer:

Step-by-step explanation:

5 years ago the sum of ages is 94

After 5 years, the new sum would have been 94 + 4*5 =  94+20 = 114.

After today, when daughter is replaced by daughter in law, the total age is 92.

Thus the difference in ages is 114 - 92 = 22.
