Q1. If the average age of father, mother & their 2 sons is 41 years. And 5 years ago, the ratio of ages of father, mother and two sons (elder and younger) was 7 : 4 : 3 : 2. Then find the sum of ages of two sons after 6 years ?

59 years.

62 years

57 years

47 years

67 years

Solution:

Let total present age of father, mother & two sons = 41 × 4 = 164 years
Let total ages, 5 years before be 16x
ATQ,
16x = 164 – 20 = 144
x = 9 years
∴ Total age of both sons after 6 years = 9 × 3 + 9 × 2+10 + 12 = 67 years

Q2. A person’s present age is 2.5 times of his son’s present age whereas the ratio of his wife’s present age to his present age is 5 : 6. 10 years ago, the ratio of person, his son and his wife’s age is 25 : 7 : 20. Find the present average age of all the three?

26 years

28 years

30 years

32 years

34 years

Solution:

Let the present age of Abhi = x years
Then, present age of Veer = (56 – x) years.
Present age of Satish = (x + 2) + 2 = (x + 4) yr.
ATQ,
⇒ x + x + 4 = 52
⇒ 2x = 48
⇒ x = 24 yr.
Present age of Veer = 32 years.

Q4. The average age of 60 students in a college was calculated as 21 years. Later, it was realized that the age of one of the students was taken as 54 years instead of 24 years. Then, find the actual average age of all the students.

19.5 year

20 year

20.5 year

21 year

Solution:

Total age of 60 students = 60 × 21 = 1260 yrs.
Actual age of 60 students = 1260 – 54 + 24 = 1230 yrs.
Actual avg. age = 1230/60 = 20.5 yrs

Q7. The age of father is 4 times the age of his son. 5 years ago the age of son was 1/5 times of his father age. Find the present age of son.

20 yrs

30 yrs

28 yrs

25 yrs

32 yrs

Solution:

Let the age of his son be x yrs
Therefore age of father = 4x yrs
Atq,
(x - 5) = (4x - 5) × (1/5)
5x - 25 = 4x – 5
x = 20 yrs
∴ age of son = 20 yrs

Q8. The sum of the ages of mother and daughter is 65 years. 10 years ago the product of their ages was 5 times the age of mother at that time. Then find the ratio of the present age of mother to the present age of daughter(age of mother is greater than 30 years).

10 : 3

12 : 5

9 : 2

3 : 1

4 : 1

Solution:

Let the present age of mother be x yr.
and that of daughter = (65 – x) yr.
ATQ,
(x – 10) (65 – x – 10) = 5 × (x – 10)
65x - x² - 10x - 650 + 10x + 100 = 5x - 50
-x² + 65x - 550 = 5x - 50
x² - 60x + 500
⇒ x = 50, 10
Required ratio = 50/15 = 10 : 3

Q10. Three years ago, average age of ‘A’, ‘B’ and ‘C’ is 27 years. Four years hence, ratio of A and C’s age is 7 : 10. If B is 6 years younger than C, then find present age of ‘A’?

24 years

27 years

30 years

28 years

36 years

Solution:

Three year ago, sum of age of A, B and C together = 27 × 3 = 81 year
Four years hence, sum of ages of A, B and C together = 81 + 7 × 3 = 102
Let Four years hence
A’s age be 7x ⇒ C’s age be 10x and B’s age be 10x–6
ATQ,
7x+10x–6+10x = 102
⇒ 27x = 108 ⇒ x = 4
Four years hence, A’s age = 7×4 = 28
Present age of A = 28–4 = 24 year

40 years

47 years

60 years

can’t be determined

None of these

Solution:

Let age of Arjun, Vikas, Rohit and Rahul is a, b, c and d respectively
Now,
b : c = 2 : 3 …(i)
b + c + d = 23 × 3 = 69 …(ii)
a + b + c + d = 25 × 4 = 100
∴ a = 31 years.
Also d – b = 13
d = b + 13
Put this value in eq. (ii)
2b + c = 56
From (i) b = 16 years, d = 29 years
c = 24 years
∴ a + d = 31 + 29 = 60 years.
