let day daughter age = D years
Son age = D + 2 years
woman age = 3 × (son + daughter age)
woman age = 3×(D+2 + D)
= 3 ×(2D +2)
= 6D + 6
after 5 years woman age will be
6D + 6 + 5= 6D + 11 years
6D + 11 = 47
6D = 36
D = 6
Age of daughter = 6 years
Age of Son = 6+2 = 8 Years

Solution:-
• The present age of the woman is 47 - 5 = 42.
• Since the woman's age is 3 times the sum of the ages of the children,
• This sum is 42/3 = 14.
• So for children ages you have two equations:
=> s + d = 14,
=> s - d = 2.
• Every time when you see two equations like these, add them.
• You will get
=> 2s = 14 + 2,
=> 2s = 16,
=> s = 16/2 = 8.
Thus son is 8 years now.
The daughter is 8 - 2 = 6 years.
i hope it helps you.
