Solution:

1.
Answer - B
Explanation

If the age of Mr. Ram 5x and 4x is the age of Mr. sham.

Then, (5x + 3) /( 4x+3) = 11/9  

⇒ 9 (5x+3) = 11 (4x+3) 

⇒ x= (33-27) = 6

So the present age of Mr. sham = 6*4 = 24 years.

 

2. 

 

Answer - A
Explanation

Let daughter present age   be x year .

in that case mother present age would be = 30x years  

30x + 18 = 3 (x+ 18) 

⇒ 27x = 36  

⇒ x = 4/3  

∴ so the present age of mother = (30* 4/3) = 40 years.

 

3.

 

Answer - A
Explanation

If the present age of ajay , vijay and sanjay is  4x , 7x and 9x years.

Total sum of  ages of ajay, vijay and sanjay  before 8 years  ago = (4x-8)+(7x-8)+(9x-8)

=(20x-24) years.

∴ 20x-24 = 56 ⇒ 20x = 80 ⇒ x= 4 

Hence,  it proves that age of ajay is 4*4 = 16 years, 

vijay (7*4) = 28 years  and sanjay  (9* 4) = 36 years. 

 

4.

 

Answer - B
Explanation

If the present age of mother is  equal to  x year.  

In that situation the daughter present age would be = 2x/5 years.

2x/5 + 8 = 1/2 (x+8) ⇒  4x+ 80 = 5x+40 ⇒ x = 40.

The mother age at the present time is = 40 years.

 

 

5.

 

Answer - C
Explanation

Before  3 year  let  bhuvan age be x years. 

3 years before , ajay age will be  2x years. 

Now Bhuwan's  age =(x+3) years and ajay  age = (2x+3) years.

(x+3)+7+(2x+3)+7 = 83 ⇒  3x+20 = 83 ⇒ 3x = 63 ⇒ x = 21 

Now the bhuwan present age = (21+3) = 24 years 

Now the ajay present age = (2 *21+3) years = 45 years.

 

6.

 

Answer - A
Explanation

If my sister age is x years. Then,

Sister  -    x 

I   -       x+4

Brother -  (x+4-7) = x-3

Father - 3 (x-3) 

Given x = 18

∴  Father's age =  3(18-3) = 45 years.

Mother age = (45-3) = 42 years.

 

7.

 

Answer - D
Explanation

V-A = A- B ⇒ V+B = 2A =48 ⇒ 24

Now,  We can say that the present age  of Mr. Ajay  is 24 years.

 

8.

 

Answer - D
Explanation

If the age of father at the present time = x years 

His son age at the present time =  (100-x) years.

x-5 / (100-x-5) = 2/1  ⇒ (x-5) = 2(95-x) ⇒ 3x = 195  ⇒ x = 65

Ratio of the ages of man and son after 10 years = (65+10)/(35+10)= 75/45 = 5/3

 

 

 

9.
 
Sol : Option C
Let the daughter's age be x and father's age be 4x.
So as per question, 4x + 5 = 3(x + 5). So x = 10.
Hence present age of daughter is 10 years and present age of father is 40 years.
So after 5 + 5 = 10 years, daughter age would be 20 years and father’s age would be 50 years.
Hence father would be 50/20 = 2.5 times of daughter’s age.
 
10.
 
Sol : Option C
Let Aman's present age be x
Aman's age before 10 years = x - 10)
Aman's age after 20 years = (x + 20)
We are given that, Aman's age after 20 years (x + 20) is 10 times his age 10 years back (x – 10)
Therefore, (x + 20) = 10 (x – 10)
Solving the equation, we get x + 20 = 10x – 100
9x = 120, x = 13.3 years
