Q 2 - In a family the average age of the father and mother is 38 years whereas the average age of father, mother and their only daughter is 28 years. Then the age of the daughter is -

A - 5 years

B - 6 years

C - 7 years

Q 3 - Six years back Seema was half of that of Rupa in age. Four years hence the respective ratio of their ages would be 3:5. How old is Rupa at present?

A - 32 years

B - 16 years

C - 40 years

D - None of these

Answer : D

Explanation

Let the present ages of Seema and Rupa be x years and y years respectively.
According to question,
(y - 6) = 2(x - 6)
Or, y - 6 = 2x - 12
Or, 2x - y = 6   ...(i)
Similarly,
(x + 4)/(y + 4) = 3/5
Or, 5x + 20 = 3y + 12
Or, 5x - 3y = - 8       ... (ii)
From equ (i) and equ (ii),
6x - 3y = 18
5x - 3y = -8
We get, x = 26 years and y = 46 years

Q 4 - 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 - C is elder to A

B - 24 years

C - 12 years

D - Data Inadequate

A + B = B + C + 12
A = C + 12
 C = A - 12

Hence, C is 12 years younger to A.

Q 5 - 10 year hence, 5:3 is the ratio of mother and daughter but 10 year before 3:1 would be the ratio of mother and daughter . Find out the mother and daughter present age of ratio?

A - 1:2

B - 1:3

C - 2:3

D - 2:5

Answer : A

Explanation

Let mother age 10 year hence be 5x years and daughter age be 3x years.
mother present age =( 5x-10) year, daughter present age = (3x-10) year
(5x-10)-10/(3x-10)-10 =3/1 ⇒ 5x-20/3x-20 = 3/1 ⇒ (5x-20) =3(3x-20) ⇒ 4x= 40 ⇒ x =10
Ratio of present age of mother and daughter =   (3*10-10)/(5*10-10) =20/40 = 1/2  =1:2

Q 6 - 18 year was the average age of A and B before the period of 3 year . if we add C in them , in that case the average become change and the new average is 22. What should be the present age of C?

A - 24 years

B - 27 years

C - 28 years

D - 30 years

Answer : A

Explanation

Sum of the ages of A and B , 3 years ago = (18*2) years =36 years
Sum of the present age of A and B = (36+3*2) year = 42 years
Sum of the present age of A, B and C = (22*3) = 66 years
Present age of C = 66- 42 = 24 years

Q 7 - If 4:1 is the ratio between mother and daughter and the sum of their age is 196. What should be the age ratio between mother and daughter after the period of 5 year?

A - 3:1

B - 10:3

C - 11:4

D - 14:5

Answer : C

Explanation

Let mother age be4 x year and her daughter age is x year.
4x*x = 196 ⇒ x2 = 49 ⇒ x = 7
Present age of mother is 7*4 = 28 year and son present age = 7 years.
Required ratio = (28+5) : (7+5) = 33 : 12   = 11 : 4

Q 8 - Before 6 year Radha got married . if we compare the marriage time with the present time , present time would be 5/4 times from the marriage time. At the present time son got 1/10 times in the comparison of his mother age . find out the present time age of his mother?

A - 2 years

B - 3 years

C - 4 years

D - 5 years

Answer : B

Explanation

Let radha age 6 year ago be x year. Then, radha present age = (x+6) years.
∴ x+ 6 = 5x/4 ⇒ 4(x+6) =5x = x =24
Present age of radha  = (24+6) = 30 years.
Son ?s present age = (1/10* 30) years = 3 years.

Q 9 - Ajay is 2 years older than brij but brij have double age in the comparison of Chaman . 27 years is the total age all of three. What should be the present age of brij?

The age of brij = 10 years.
