The sum of the present ages of a father and his daughter is 80 years. Eight years ago, the father's age was seven times the age of his daughter. Eight years from now, what will be the daughter's age?
Let the present age of the daughter be x years.
Then, the present age of the father is (80 - x) years.
From the condition: Eight years ago, the father's age was seven times the daughter's age.
Equation: (80 - x - 8) = 7(x - 8)
(80 - x - 8) = 7(x - 8)
72 - x = 7x - 56
72 + 56 = 7x + x
128 = 8x
x = 128 / 8
x = 16
The daughter's present age is 16 years.
Daughter's age after 8 years = 16 + 8 = 24 years.
The daughter's age eight years from now will be 24 years.
The sum of ages of P and Q is 15 years more than the sum of ages of Q and R. How many years younger is R as compared to P?

=> R = P - 15
Hence, R is "15" years younger than P.
The present age of Rahim is five times the present age of his daughter, Savita. Seven years from now, Rahim will be three times as old as Savita. What is the present age (in years) of Rahim?
Substitute (R = 5S) into (R+7 = 3(S+7)):
5S + 7 = 3S + 21
2S = 14
S = 7
Then
R = 5S = 5 × 7 = 35

After 8 years, the sum of the years of service of A, B, C and D will be 78 years. Before 4 years, the sum of years of service of B and C was 18 years. What is the current length of service of A, if the years of service of D is 12 years?
Total sum of present years of service of A + B + C + D = 78 – (8) × 4 = 46 years
Total sum of present years of service of B + C = 18 + (4) × 2 = 26 years
Years of (A + D) = 46 – 26 = 20 years
Years of A = 20 – 12 = 8 years
