Age

Age of the past, from the birth of someone till date, is called age, that is, the age tells us when he was born and how long he lived.

Questions of this chapter are discussed in the context of the age of two persons, in which the relationship between the two ages before and after some time is shown. Normally two people have fathers and sons. Generally questions related to the age of both of these questions are asked in the examination. In order to solve the questions, the candidates have to know the age of both the persons present or a few years ago or a few years later. Candidates have to know the sum of both the average age / age of both.

 

Hypothesis

1. If a person has to remove the age of x years, then deduct from the present age.

Example: If the current age of Rama is 20, then to reduce the age of 6 years, we will deduct 6 out of 20, i.e. 6 years ago Ram was 14 years old.

2. If a person has to remove the age of x years then add x to the current age of that person.
Example:
If the current age of Rama is 20 years, then after 4 years, it will be 20+ 4 i.e., 24 years.

3. The difference of age is always constant in any two individuals. That is, if the present age of the son is 25 years less than the current age of the father, it will always be 25 years short.

 

– Let us now see an example of the questions asked in the examination based on the above facts.

Example 1. After five years my father will be 55 years old. Tell them 8 years ago what was their age?

Solution: My father’s current age = 55 – 5 = 50 years

∴ 8 years preceding their age = 50 -8 = 42 years.

 

Example 2. A, B is twice as big in age. Four years ago, the age of C was twice the age of A. In four years, age of A will be 32 years, then what is the current age of B and C?
(a)
10, 50 (b) 9, 46 (c) 14, 52 (d) 16 , 54

Solution: (c) At Question level, age of A = 4 years = 32 years
∴ Current age = 32 – 4 = 28 years
Current age of ∴ B = 28/2 = 14 years (twice than A, B)
∴ Current Age of C = (current age of A – 4) × 2 + 4 = (28 – 4) × 2 + 4 = 52 years
