What is the ratio of father's age to son's age if their ages are 35 years? ›

The average age of man and his son is 35 years. The ratio of their ages is 5:2 respectively.

After five years, the ratio of their ages (father's age and son's age) will become 7: 2. Hence, Present age of son = x = 5 years. Present age of father = 6x = 6(5) = 30 years.

∴ the son's age (Y) = 5 yrs and father's age (X) = 30 yrs.

If the age of a person is 'x', then 'n' years after today, the age = x + n. Similarly, n years in the past, the age of this would have been x – n years. Answer: Suppose that the present age of the son is = x years. Then the father's age is (60 -x) years.

Hence, father age =45 years. Father's age is three times the sum of age of his two children. After 5 years his age will be twice the sum of ages of two children. Find the age of father.

When the current age is x, age n years later = x + n. When the current age is x, age n years ago = x – n. The ages in a ratio a: b will be ax and bx. when the current age is x,1/n of the age is x/n.

Answer. The theory of financial ratios was made popular by Benjamin Graham, who is popularly known as the father of fundamental analysis.

Detailed Solution

The ratio of their ages before some years is 3 : 5. Calculation: Let, x years ago, the ratio of their ages would have been 3 : 5 respectively. ∴ 10 years ago the ratio of their ages 3 ∶ 5.

Therefore, the present age of father = 36 years and the present age of son = 9 years. Q. The sum of ages of a father and his son is 45 years. Five years ago, the product of their ages (in years) was 124.

Therefore, we get the value of x as 45, which means the age of the father is 45 years.

What is the age of father if the sum of the ages? ›

If the sum of the ages of a father and his son in years is 65 and twice the difference of their ages in years is 50, then the age of the father is: 45 years.

The study, published 30 August in Human Reproduction , used a federal repository of nearly 170 million birth records to find that the average dad is now 30.9 years old at their child's birth—and that 9% of newborns' fathers are at least 40 years old.

Turns out, just as women enter the high risk category at the age of 35, the same is true for men. At this age, they start to develop issues with their sperm that can affect the offspring's overall health.

The average age of the man and his son is 28 years. Hence their total age =56 years. Their ages are in the ratio of 3:1 hence Father's age is 3/4×56 = 42 years and Son's age is 14 years.

Furthermore, fathers were consistently older, at 30.7 years on average, than mothers, at 23.2 years on average, but the age gap has shrunk in the past 5,000 years, with the study's most recent estimates of maternal age averaging 26.4 years.
