Given that :- The age of Ram = 8 years.
The age of Geeta = Age of Ram - 2 years
The age of Geeta = age of Ram - 2 years = 8 ? 2 = 6 years.
According to question ,
? Age of Kamal = 5 x Age of Geeta
The age of Kamal = 6 × 5 = 30 years.
Le t us assume the present Nisha's age be P years.
Then Nisha's younger brother Age will be P - 4.
Then father present age = 38 + P
Mother present Age = 36 + P - 4 = 32 + P
According to question,
Difference in age of parents = Father age - Mother age
Difference in age of parents = 38 + P - (32 + P)
Difference in age of parents = 38 + P - 32 - P = 6 years.
Let us assume the present age of the person be P years.
3 years hence the age of person = P + 3
3 years ago the age of person = P - 3
According to question,
Take my age three years hence, multiply it by 3 and then subtract 3 times my age three years ago,
= 3(P + 3) - 3(P - 3)
= 3P + 9 - 3P + 9
= 18 years
Hence, age of the person = 18 years
Let us assume the present ages of son be P then mother's age will be 5P years.
After 4 years, Son' age = P + 4
After 4 years, Mother' age = 5P + 4
According to question,
5P + 4 + P + 4 = 44
? 6P = 36
? P = 6 years
Let us assume the present age of child is P years.
Then according to question,
I was as old as you are at present at the time of your birth.
Father's age were at the time of son's birth = P years
Again According to question
Present age of father = 38
Father's age were at the time of son's birth + Present age of Son = 38
P + P = 38
2P = 38
? P = 19 years
Hence, 5 years ago the age of son was 19 - 5 = 14 years
Suppose the present age of son is P years.
Therefore, present age of the father = 4P years
According to question
The present age of son + 3 years = 15
? The present age of son ( P ) = 15 ? 3 = 12 years
The present age of father = 4P = 4 × 12 = 48 years
? The present age of man's wife = The present age of father - 3 = 48 ? 3 = 45 years
Suppose the age of son is P years
Therefore, the age of father will be 5P + 1
According to question ,
? 4( age of son + 3 ) ? 2 years = age of father + 3 years
? 4 ( P + 3 ) ? 2 = ( 5P + 1 ) + 3
? 4P + 12 ? 2 = 5P + 4
? 10 ? 4 = 5P ? 4P
? P = 6
Age of father = 5P + 1 = 5 × 6 + 1 = 31 years
Hence , the age of father is 31 years .
Given that :- The average age of 19 boys in a class = 21 years
Total age of 19 boys = 19 × 21 = 399 years
The average age of 19 boys and teacher = 22 years
Total age of 19 boys and teacher = 20 × 22 = 440 years
?Teacher's age = Total age of 19 boys and teacher - Total age of 19 boys
Teacher's age = 440 ? 399 = 41 years
Hence , the age of teacher is 41 years .
Suppose the age of son at present = P years
? Present age of the father = Present age of son + 30 years
Present age of the father = P + 30 years
Age of father at the birth of his son = Present age of the father - Present age of son = ( P + 30 ) ? P = 30 years
