A person said : Take my age three years hence, multiply it by 3 and then subtract 3 times my age three years ago and hence everybody will know how old I am ". The age of person in years is:

Let us assume the present ages of son be P then mother's age will be 5P years.
After 4 years, Son' age = P + 4
After 4 years, Mother' age = 5P + 4
According to question,
5P + 4 + P + 4 = 44
? 6P = 36
? P = 6 years

Let us assume the present age of child is P years.
Then according to question,
I was as old as you are at present at the time of your birth.
Father's age were at the time of son's birth = P years
Again According to question
Present age of father = 38
Father's age were at the time of son's birth + Present age of Son = 38
P + P = 38
2P = 38
? P = 19 years
Hence, 5 years ago the age of son was 19 - 5 = 14 years

Let us assume the age of youngest child be P years.
Then according to question,
The age of 5 children born after every 3 years will be P , P + 3,
P + 6, P + 9, P + 12.
Now as we know from the given question
The sum of the ages of 5 children born at the interval of 3 years each is 50 years
P + (P + 3) + (P + 6) + (P + 9) + (P + 12) = 50
? 5P + 30 = 50
? 5P = 20
? P = 4 years

Let us assume Q age is Q years , R age is R years and T age is T years.
According to question,
Q is as much younger than R as he is older than T
Age of Q - T = R - Q
? Q = (R + T)/2
If sum of the ages of R and T is 50 years.
Hence, age of Q = 50/2 = 25 years
Here, absolute value of age of R is not known.
So the difference between R and Q's age cannot be determined. Hence, data is inadequate.

Let the present age of Ram be x years; then
8 years ago Ram age = x - 8
According to question,
His present age is 6/5 times his age at the time of marriage.
x =( x - 8) 6/5
? 5x = 6x - 48
? x = 48
Age of Ram at the time of his marriage = 48 - 8 = 40
According to question,
Ram's sister was 10 years younger to him at the time of his marriage
Hence, Ram's sister age at the time of his marriage = 40 - 10 = 30 years.
So Present age of Ram's Sister = 30 + 8 = 38

Le t us assume the present Nisha's age be P years.
Then Nisha's younger brother Age will be P - 4.
Then father present age = 38 + P
Mother present Age = 36 + P - 4 = 32 + P
According to question,
Difference in age of parents = Father age - Mother age
Difference in age of parents = 38 + P - (32 + P)
Difference in age of parents = 38 + P - 32 - P = 6 years.

Given that :- The age of Ram = 8 years.
The age of Geeta = Age of Ram - 2 years
The age of Geeta = age of Ram - 2 years = 8 ? 2 = 6 years.
According to question ,
? Age of Kamal = 5 x Age of Geeta
The age of Kamal = 6 × 5 = 30 years.

Suppose the present age of son is P years.
Therefore, present age of the father = 4P years
According to question
The present age of son + 3 years = 15
? The present age of son ( P ) = 15 ? 3 = 12 years
The present age of father = 4P = 4 × 12 = 48 years
? The present age of man's wife = The present age of father - 3 = 48 ? 3 = 45 years

Suppose the age of son is P years
Therefore, the age of father will be 5P + 1
According to question ,
? 4( age of son + 3 ) ? 2 years = age of father + 3 years
? 4 ( P + 3 ) ? 2 = ( 5P + 1 ) + 3
? 4P + 12 ? 2 = 5P + 4
? 10 ? 4 = 5P ? 4P
? P = 6
Age of father = 5P + 1 = 5 × 6 + 1 = 31 years
Hence , the age of father is 31 years .
