Aptitude - Problems on Ages - Discussion

Ayesha's age = x.
Father's age = 38-x.
Brother's age = x-4.
Mother's age = 36-(x-4).
Parents age difference = (38-x)-(36-(x-4)).
= 38 - x - 36 + x + 4.
= 6.

When the father's age is 38 Aysha's age 0.
When Mother's age is 36 Aysha's age 4.
So that when the father 38 then the mother 32,
So the difference between their parents is 38-32 = 6 years.

Thanks @Palavi.

Let Ayesha be A, father age be F.
Her Father will be F = 38-A.
And Ayesha s brother, 4 yr younger than Ayesha be A-4.

Her mother = 36-(A-4).
Parents difference = 38-A-(36-A-4).
= 38-A-36+A+4,
=42-36,
= 6yr.

Such a simple and great explanation @Pallavi.

Thank you so much.

According to me, the solution is;

Ayesha born father age 38 years means ration is 1x:38x assume.

Why you minus 4 again in this value.

Again skip to this part.,
Her brother is 4 years younger than her
So here, Ayesha and brother ratio is assumed.
4x:1x.
No need to work on brother age.

According to the question, it's self says at a time if Ayesha born her father age is 38 years and mother's age is 36years and her brother 4 years younger than her.

So parents diff is 38 - 36 = 2 years.

S=x,D=x+4,
F=x+4+38=42,
M=x+36,
F-M=x+42-x-36 = 6years.

Ayesha's age = 0,
Father's age = 38.
Mother's age = I have no clue from the info.

Now they say bro is 4 years younger to Aisha meaning, she ages by 4 years so will her dad and her mom will age by 4 years from the time she was born.

Ayesha brother is 0 years.
Ayesha = 4 years
Ayesha father = 38+4 = 42
Ayehsa mother = 36 (Given when a bro is born her age is mentioned )

So by the mother age, now we can re-trace her age 4 years back = 32 years.

So a difference of father and mother = 6 years ( 42-36).

Ayesha's age = 0
Father's age = 38
Mother's age = 36

Ayesha is 4 years
4 years after =0
Mother's age =32.

Take Ayesha age at a time to find the difference.

Ayesha age=0 then father age=38.
Ayesha's brother, who is younger than him by 4 years.
When Ayesha'brother born his mother age =36 that time Ayesha age is 4 year.
So back to four years that time Ayesha age is 0 and his mother age is 32.
Now, find the difference of father and mother age because of now Ayesha age become=0.
To find differene of age either Ayesha age for his brother age must be =0<<<<<.
