Question

Ayesha’s father was 38years of age when she was born while her mother was 36 years old when her brother 4 years younger to her was born. What is the difference between the ages of her parents?

Answer 1

Hint:We just have to use the given information given in twisted form. When Ayesha was born her father’s age was given. When a brother is born, her mother’s age is given, the relation between Ayesha’s age and his brother's age is also given, this means indirectly the relation between Ayesha’s mother and father is given, just calculate the difference.

Complete step by step answer:
Ayesha’s father was 38 years of age when she was born.
I.e. When Ayesha was 0 years of age her father was 38 years old.
Now her mother was 36 years of age when her brother 4 year younger to her was born.
So at the time of the birth of her brother the age of Ayesha is 4 years.
So the age of mother at the time of birth of Ayesha (i.e. when Ayesha was 0 years of age) is (36 – 4) = 32 years old.
So the difference (D) of ages of her parents is
D = age of father at the time of Ayesha birth – age of mother at the time of Ayesha birth.
$ \Rightarrow D = 38 - 32 = 6$
So the age difference of her parents is 6 years.
So this is the required answer.

Note – Such type of questions are generally found in aptitude tests, only the data is manipulated and twisted in such a way that confuses the observer. It is always advised to write down all the given relations first, this reduces the chances of making mistakes to a greater extent.
