Q 1 - The ratio between the ages of Ram and Mohan is 4:5 and that between Mohan and Anil is 5:6. If sum of the ages of three be 90 years, how old is Mohan?

### Answer : C

### Explanation

Ram : Mohan = 4:5 Mohan : Anil = 5:6 Ram : Mohan : Anil = 4:5:6 Therefore, Mohan?s age = (5/15) * 90 = 30 years

Q 2 - The ratio of the present ages of Sunita and Vinita is 4:5. Six years hence the ratio of their ages will be 14:17. What will be the ratio of their ages 12 years hence?

### Answer : A

### Explanation

Suppose the present ages of Sunita and Vinita be 4x years and 5x years respectively. Six years hence (4x + 6)/(5x + 6) = 14/17 Or, 68x + 102 = 70x + 84 Or, 2x = 18 Or, X = 9 Ratio of ages of Sunita and Vinita after 12 years = (4x + 12) : (5x + 12) = (36+12) : (45+12) = 48:57 = 16:19

Q 3 - A father is 30 times older than his son. 18 years later, he will be only thrice as old as his son. Father?s present age in years is:

### Answer : C

### Explanation

Let the age of the son be x years. So, father's age = 30x years. As per question, after 18 years, 30x + 18 = 3 (x + 18) Or, 27x = 54 - 18 Or, x = 36/27 = 4/3 Therefore father's present age = 30*4/3 = 40 years

Q 4 - If 3:4 is the present age ratio of anil and varun but 5 year later , the ratio of their age change and become 4:5 . Find out the present age of varun ?

### Answer : C

### Explanation

If anil age is 3x year and 4x is the varun age. 3x+5/ 4x+5 =4/5 ⇒5(3x+5) = 4(x+5) ⇒ 15x+25 = 16x+20 ⇒ x= 5 Varun age = (4*5) =20 year

Q 5 - If 100 year is equal to the sum of the ages of father and son. 2:1 was the ratio of father and son before the period of 5 years . Find out the ratio of ages which would be after the period 10 year.

### Answer : B

### Explanation

If x is the father age ,then son age will be (100-x) x-5/ (100-x)-5 =2/1 ⇒ (x-5)= 2(95-x) ⇒ x =-5= 190 -2x ⇒ 3x =195 ⇒ x =65 father age = 65 yrs. And son age = 100-65 = 35 year required ratio = (65+10) / (35+10) =75/45 = 5:3

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?

### 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 Ram and Sham have 36 year and 16 year age . After how much time ram age would be double as old as sham ?

### Answer : D

### Explanation

Let it be in x years. Then, 36+x = 2(16+x) ⇒ x =4

Q 8 - Yusuf is as much younger to ajay as he is older to pawan , if 48 year is the sum of ajay and pawan then what should be the present age of yusuf?

### Answer : B

### Explanation

Given A-Y = Y-P ⇒ A+P = 2Y Also A+P = 48 Year . so, 2j = 48 ⇒ y = 24 Hence, yusuf is 24 year old.

Q 9 - Before the period of 16 year, my grandfather was 8 times older in the comparison of me. He would be 3 times of my age 8 years now. Find out the ratio of my grandfather and my age before the period of 8 year.

### Answer : D

### Explanation

Let my age 16 yrs ago be x years. My grandfather age at that time = 8x years My present age = (x+16) yrs. My grandfather present age = (8x+16) years. 3(x+16+8)= (8x+16+8) ⇒ 3x+72 = 8x+24 ⇒ 5x = 48 ⇒ x = 48/5 Ratio of our ages 8 yrs ago = (x+16-8) /(8x+16-8) = x+8/ 8x+8 (48/5+8)/ (8* 48/5 +5) = 88/424 = 11 :53.

Q 10 - 15 year hence, a man will be just 4 times as old as he was 15 years ago . His present age is

### Answer : A

### Explanation

Let the present age of the men be x years. then (x+15) = 4(x-15) ⇒ 3x= 75 ⇒ x =25 Hence, the present age of the man is 25 years.
