Formulas on Ages Problems

If the present age is y, then n times the present age = ny.

If the present age is x, then age n years later/hence = x + n

If the present age is x, then age n years ago = x – n

The ages in a ratio a: b will be ax and bx

If the current age is y, then $1/n$ of the age is $y/n$

Questions and Answers Based On Age Problem

Question-1)

The ratio of the present ages of Sukanya and her mother is 2:9. The mother's age at the time of Sukanya’s birth was 28 years. Find their present ages.

Answer:

Present ratio of ages between Sukanya and her mother is 2: 9.

Let the actual ages of Sukanya and her mother be $2x$ and $9x$.

The age of her mother at the time of Sukanya’s birth was 28 years.

Therefore, the difference between Sukanya and her mother's age will always remain 28 years.

∴ $9x – 2x = 28 ⇒ x = 4$

Hence their present ages are 8 and 36 yrs.

Question-2)

The ratio of Bikash's age to Prakash's age is equal to 4 : 3. Ashok will be 26 years old after 6 years. How old is Prakash now?

Answer:

Let Bikash's age = $4x$ years

and Prakash's age = $3x$ years

From question, $4x + 6 = 26 ⇒ x = 5 $

Prakash's age = $3x =3 × 5 = 15$ years

Question-3)

The ages of Amiya and Srini are in the ratio of 7:6, and the difference between their ages is 3 years. What is the sum of their ages?

Answer:

Let the present of Amiya and Srini are 7k yr and 6k yr, respectively.

∴ 7k - 6k = 3

∴ k = 3

Hence, required sum = 7k + 6k = 21 x 18 = 39 years

Question-4)

P is two years older than Q who is twice as old as R. If the total of the ages of P, Q and R be 27, the how old is Q?

Answer:

Let R's age be $x$ years. Then, Q's age = 2x years. P's age =$ (2x + 2)$ years.

∴ $(2x + 2) + 2x + x$ = 27

⇒ $5x = 25 ⇒ x = 5$

Hence, Q's age =$ 2x $= 10 years

Question-5)

The sum of the present ages of a father and his son is 60 years. Six years ago, father's age was five times the age of the son. After 6 years, son's age will be?

Answer:

Let the present ages of son and father be $x$ and $(60 -x)$ years respectively.

Then, $(60 - x) - 6 = 5(x - 6)$

⇒ $54 - x = 5x - 30$

⇒ $6x = 84$

⇒ $x = 14$

∴ Son's age after 6 years = $(x + 6)$ = 20 years
