A father said his son , " I was as old as you are at present at the time of your birth. " If the father age is 38 now, the son age 5 years back was :
A) 14  B) 19 
C) 33  D) 38 
A) 14
Explanation:
Let the son's present age be x years .Then, (38  x) = x => x= 19.
Son's age 5 years back = (19  5) = 14 years
The sum of the present ages of a father and his son is 60 years. five years ago, father's age was four times the age of the son. so now the son's age will be:
A) 5  B) 10 
C) 15  D) 20 
C) 15
Explanation:
Let the present ages of son and father be x and (60 x) years respectively.
Then, (60  x)  5= 4(x  5)
55  x = 4x  20
5x = 75 => x = 15
Present ages of Sameer and Anand are in the ratio of 5 : 4 respectively. Three years hence, the ratio of their ages will become 11 : 9 respectively. What is Anand's present age in years?
A) 24  B) 27 
C) 40  D) cannot be determined 
A) 24
Explanation:
Let the present ages of Sameer and Anand be 5x years and 4x years respectively.
Then, 5x+3/4x+3 = 11/9
9(5x + 3) = 11(4x + 3)
45x + 27 = 44x + 33
45x  44x = 33  27
x = 6.
Anand's present age = 4x = 24 years.
A person's present age is onefifth of the age of his mother. After 7 years, he will be one third of the age of his mother. How old is the mother at present (in years)?
A) 35  B) 40 
C) 45  D) 50 
D) 9
Explanation:
Let the mother's present age be x years.
Then, the person's present age = 1/5 x years. (1/5) x = 7 = (1/3)(x+7)
⇒ 3x + 105 = 5x + 35
⇒ x = 35
The ratio of Seema's age to the age of her mother is 5:12. The difference of their ages is 21 years. What will be the ratio of Seema's age and her mother's age after three years?
A) 3 : 7  B) 13:7 
C) 6:13  D) 7:3 
c) 6:13
Explanation:
The ratio of Seema's age to the age of her mother is 5:12.
The difference of their ages 12x  5x = 21, ⇒ x= 3
∴ Ratio of their ages after 3 years = 5x+3: 12x+3
⇒ 5*3+3:12*3+3
⇒ 18:39 ⇒ 6:13
The ratio of the father's age to the son's age is 3 : 1. The product of their ages is 147. The ratio of their ages after 5 years will be?
A) 15:7  B) 13:6 
C) 26:17  D) 27:5 
B) 13:6
Explanation:
Let father's age be 3x and son's age be x years
=>3X*X=147
=>X^2=49 => 7
Father's age after 5 years = 3x + 5 = 26 years
Rajeev's age after 15 years will be 5 times his age 5 years back. What is the present age of rajeev?
A) 12  B) 14 
C) 22  D) 10 
D) 10
Explanation:
Let Rajeev's present age be x years.
Rajeev's age after 15 years = (x + 15) years.
Rajeev's age 5 years back = (x  5) years
Then ATQ,
x + 15 = 5 (x  5)
x + 15 = 5x  25
=> x = 10
Hence, Rajeev's present age = x = 10 years.
Sivagami is 2 years elder than Meena. After 6 years the total of their ages will be 7 times of their current age. Then age of Sivagami is :
A) 19 years  B) 17 years 
C) 15 years  D) data inadequate 
D) data inadequate
Explanation:
Then Sivagami’s age = A + 2
After 6 years the total of their ages will be 7 times of what?
Not clear.
So the given data are inadequate.
A man is 24 years older than his son. In two years, his age will be twice the age of his son. The present age of his son is
A) 20  B) 21 
C) 22  D) 23 
C) 22
Explanation:
Let the son's present age be x years. Then, man's present age = (x + 24) years
=> (x + 24) + 2 = 2(x + 2)
=> x + 26 = 2x + 4
So, x = 22
The ages of Krish and Vaibhav are in the proportion of 3 : 5. After 9 years, the proportion of their ages will be 3 : 4. Then the current age of Vaibhav is: r
A) 10  B) 13 
C) 15  D) 18 
C) 15
Explanation:
Krish’s age = 3A and Vaibhav’s age = 5A
(3A+9)/(5A+9) = 3/4
4 (3A + 9) = 3 (5A + 9)
A = 3
Therefore, Vaibhav’s age = 15 years.
The sum of the ages of a son and father is 56 years after four years the age of the father will be three times that of the son. Their ages respectively are:
A) 12 years, 44 years  B) 16 years, 42 years 
C) 16 years, 48 years  D) 18 years, 36 years 
A) 12 years, 44 years
Explanation:
Present ages of son and father be x years (56 x)years
(56 x +4) = 3(x + 4) or 4x =48 or x = 12
Ages are 12 years, 44 years
A person was asked to state his age in years. His reply was, 'Take my age three years hence, multiply it by 3 and then subtract three times my age three years ago and you will know how old I am.' What was the age of the person?
A) 18 years  B) 20 years 
C) 24 years  D) 32 years 
A) 18 years
Explanation:
Let the present age of the person be x years.
Then, 3(x + 3)  3(x  3) = x
3x + 9  3x + 9 = x => x = 18
The total age of A and B is 12 years more than the total age of B and C. C is how many years younger than A?
A) 12  B) 24 
C) C is elder than A  D) Data inadequate 
A) 12
Explanation:
(A + B)  (B + C) = 12
A  C = 12
A is 2 years older than B who is twice as old as C. If the total of the ages of A, B and C be 27, then how old is B?
A) 7 years  B) 8 years 
C) 9 years  D) 10 years 
D) 10 years
Explanation:
Let C's age be x years
Then, B's age = 2x years
A's age = (2x + 2) years
(2x + 2) + 2x + x = 27
5x = 25 => x = 5
Hence, B's age = 2x = 10 years
The sum of the ages of 5 children born at the intervals of 3 years each is 50 years. what is the age of the youngest child ?
A) 4  B) 8 
C) 10  D) None 
A) 4
Explanation:
Let x = the youngest child. Each of the other four children will then be x+3, x+6, x+9, x+12.
We know that the sum of their ages is 50
so, x+(x+3)+(x+6)+(x+9)+(x+12) = 50
=> x= 4
The youngest child is 4 years old.
Six years ago, the average age of A, B, C, and D was 30 years. When E joined them, the average of all the five becomes 40 years. The age of E is
A) 49 years  B) 35 years 
C) 42 years  D) 56 years 
D) 56 years
Explanation:
6 years ago average age of A,B,C,D = 30 years
∴ 6 years ago total age of A, B, C, D = 30 x 4 = 120 years
∴ Total present age of A, B, C, D = 120 + 6 x 4 = 144 years
If E's present age is x years, (144 + x) / 5 = 40
Therefore, X= 56.
The average age of a couple is 24 years when they were married five years ago but now the average age of the husband, wife and child is 20 years(the child was born during the interval). What is the present age of the child ?
A) 2 yrs  B) 4 yrs 
C) 3 yrs  D) 5 yrs 
A) 2 yrs
Explanation:
29 x 2 = 58
20 x 3 = 60
2 years
Therefore, the age of child is 2 years.
Mother’s age today is thrice as her daughter’s. After 10 years it would be just double. How old is the daughter today ?
A) 8 years  B) 9 years 
C) 10 years  D) 11 years 
C) 10 years
Explanation:
Then Sivagami’s age = A + 2
After 6 years the total of their ages will be 7 times of what?
Not clear.
So the given data are inadequate.
The age of a man is 3 times of his son. Six years ago, the man was seven times old as his son was at that time. The present age of man is
A) 36 years  B) 27 years 
C) 48 years  D) 39 years 
B) 27 years
Explanation:
Let the son's age be x years and the father's age be 3x years.
⇒ (3x6) = 7(x6)
⇒ 3x6 = 7x42
⇒ x = 9
∴ Present age of the father =3x= 3*9= 27 years
The present ages of three persons in proportions 4 : 7 : 9. Eight years ago, the sum of their ages was 56. Find their present ages (in years). r
A) 8, 20, 28  B) 16, 28, 36 
C) 20, 35, 45  D) None of these 
C) 15
Explanation:
Let their present ages be 4x, 7x and 9x years respectively.
Then, (4x  8) + (7x  8) + (9x  8) = 56
20x = 80
x = 4.
Their present ages are 4x = 16 years, 7x = 28 years and 9x = 36 years respectively.

A) 18 years  B) 28 years 
C) 24.5 years  D) None of these 
C) 24.5 years
Explanation:
Let Rahul's age be x years.
Then, Sachin's age = (x  7) years.
X7 : X = 7:9
9x  63 = 7x
2x = 63 x = 31.5
Hence, Sachin's age =(x  7) = 24.5 years.
When I was 24, my mother was twice my age. Now I am 44, how old is my mother?
A) 84  B) 48 
C) 9 years  D) 88 
C) 68

A) 4 years  B) 3 years 
C) 2 years  D) 1 years 
A) 4 years
Explanation:
Let Ishika and her daughter present ages be p and q
p = 4/3(p  9)
=> p = 36 years
Hence, Ishika's present age = 36 years and Her daughter's present age = 1/6 x 36 = 6 years
Now, required her daughter’s age three years ago = 6  3 = 3 years.
Dinesh is younger to Roshan by 9 years. If their ages are in the respective ratio of 4:5, how old is Dinesh?
A) 36 years  B) 23 years 
C) 29 years  D) Cannot be determined 
A) 36 years
Explanation:
Let Roshan's age be x years.
Then, Dinesh 's age = (x  9) years.
(x  9)/x = 4/5
x = 45 Hence, Dinesh's age = (x  9) = 36 years.
Shivani is 60 years old and Ritu is 80 years old. How many years ago their age ratio was 4:6?
A) 10 years  B) 15 years 
C) 20 years  D) 25 years 
C) 20 years
Explanation:
Let us assume x years ago
At present Shivani is 60 years old and Ritu is 80 years old.
X years ago : Shivani’s age = (60x) and Ritu’s age (80x)
Ratio of their ages x years ago was 4:6
(60x) / (80x) = 4/6
6 (60x) = 4 (80x)
3606x = 3204x
6x – 4x = 360 – 320
2x = 40 =>x = 20
Therefore, 20 years ago their age ratio was 4:6
Saransh is 50 years old and Nazma is 40 years old. How long ago was the ratio of their ages 3:2?
A) 20 years  B) 30 years 
C) 40 years  D) 25 years 
A) 20 years
Explanation:
Here, we have to calculate: How many years ago the ratio of their ages was 3:2. Let us assume x years ago
x years ago: Saransh’s age = (50 – x) and Nazma's age = (40 – x)
Given, the ratio of their ages was 3:2
(50x) / (40x) = 3/2
Solving, we get: x = 20
Therefore, the answer is 20 years.
What is John’s present age, if after 10 years his age will be 5 times his age 5 years back.
A) 6.2 years  B) 7.7 years 
C) 8.7 years  D) 10 years 
C) 8.7 years
Explanation:
Let John’s present age be x
John’s age before 5 years = (x  5)
John’s age after 10 years = (x + 10)
We are given that, John’s age after 10 years (x + 10) is 5 times his age 5 years back (x –5)
Therefore, (x + 10) = 5 (x – 5)
Solving the equation, we get
x + 10 = 5x – 25
4x = 35 x = 8.75 years
James present age is 2/7th of his fathers present age. James brother is three year older to Jame. The respective ratio between present ages of James father and James brother is 14:5. What is the present age of James? r
A) 12 years  B) 13 years 
C) 14 years  D) 15 years 
A) 12 years
Explanation:
James father present age = x
James age = 2/7 x
James brother age = 2x/7 + 3
x = 42
=> 2x/7 = 12 yrs
