P – 8 = S + D —(1)
6D + 30 = 7S + 35 —(2)
H = 7 + P
H = 3S
3S = 7 + P —-(3)
Solving equation (1),(2) and (3) D = 23
Therefore, the present age of the daughter is 23 years

Given data:
Pranathi's husband is 7 years elder to her
Pranathi's husband's present age = 3 * Son's present age

Let's assume:
Son's present age = x years
Daughter's present age = y years
Pranathi's present age = z years

Calculating Pranathi's husband's present age:
Pranathi's present age = x + y (as 8 years ago, Pranathi's age was equal to the sum of her son and daughter's present ages)
z = x + y
Pranathi's husband's present age = z + 7
Pranathi's husband's present age = (x + y) + 7
Pranathi's husband's present age = (x + y) + 7
Pranathi's husband's present age = x + y + 7
Pranathi's husband's present age = x + y + 7
Pranathi's husband's present age = 3x (as per the given data)
Therefore, 3x = x + y + 7
2x = y + 7
y = 2x - 7

Calculating the daughter's present age:
5 years hence, the ratio of daughter's age to son's age will be 7:6
(y + 5) / (x + 5) = 7 / 6
6(y + 5) = 7(x + 5)
6y + 30 = 7x + 35
6(2x - 7) + 30 = 7x + 35
12x - 42 + 30 = 7x + 35
12x - 12x = 35 - 30 + 42
0 = 47
This equation does not satisfy, so let's recheck the calculations.
