The age of a man is 4 times that of his son. Five years ago, the man was nine times as old as his son was at that time. The present age of the man is?

Let the present age of the Vikas be x years. Then,
17 - 5 = (x - 5)/3
? x - 5 = 36
? x = 41 years

Let Rita's age of 2 years ago be x years.
? Pushpa's present age = 2x years
? 2x - (x + 2) = 2
? x = 4
? Pushpa's present age = 8 years.

Let Chandravati's age 10 years ago be x years.
? mothere's age 10 years ago = 4x years
From Question 2(x + 20) = (4x + 20)
? x = 10
? Present age of Chandravati = (x + 10) = 20 years

Let the present ages of mother and her daughter are ( x + 25 ) and x years respectively ; then 6( x - 5 ) = x + 25 - 5 ? 6x - 30 = x + 20 ? 5x = 50 ? x = 10
Hence, the age of the mother = 10 + 25 = 35 years

Let us assume x years ago, the ratio of their ages was 3 : 5, then
According to question,
(40 - x)/(60 - x) = 3/5
? (40 - x) 5 = 3 (60 - x)
? 200 - 5x = 180 - 3x
? 2x = 20
? x = 10 years

Let the present age of the father and son be x years and (45 - x)years respectively.
Then, (x - 5)(45 - x - 5) = 4(x - 5)
? -x² + 41x - 180 = 0
? (x - 5)(x - 36) = 0
? x = 36
? The present ages of father and son are 36 years and 9 years respectively.

Let Ramesh's present age be x years. Then Shyam's present age = 3x years.
? 2(x + 12) = (3x + 12)
? x = 12
Hence, Shyam's present age is 36 years.

Let the present ages of B and A be x years and (x + 9) years respectively.
Then, (x + 9 + 10) = 2(x - 10)
? x = 39

Let the present ages of son and father be x years and (56 - x) years respectively.
Then, (56 - x + 4) = 3(x + 4)
? 4x = 48
? x = 12
So, their present ages are 12 years, 44 years respectively.

Let A's age 10 years ago = x years
Then, B's age 10 years ago = 2x years
? (x + 10) / (2x + 10) = 3 / 4
? 4(x + 10) = 3(2x + 10)
? x(6 - 4) = 40 - 30
? x = 5

&ther4; Total of their present ages = (x + 10) + (2x + 10)
= (3x + 20)
= 35 years
