A. 15

B. 17

C. 18

D. 19

E. 16Answer –**A. 15**

**Explanation :**

Present ages of son and Suresh be x and (60 -x) years respectively.

(60 – x) – 5= 4(x – 5)

55 – x = 4x – 20

5x = 75

x = 15**In a college, the average age of students of a class is 15.8 years. The average age of boys in the class is 16.4 years and that of the girls is 15.4 years. The ratio of number of boys to the number of girls in the class is**

A. 3:5

B. 2:3

C. 2:1

D. 2:7

E. 3:2Answer –**B. 2:3**

**Explanation :**

Number of boys = x

Number of boys = y

(x*16.4 + y*15.4)/x + y = 15.8

16.4x + 15.4y = 15.8x + 15.8y

0.6x = 0.4y

x:y = 2:3**If two times of the Ria’s age in years is included to her mother’s age, the total is 70 and if two times of the mother’s age is included to the Ria’s age, the total is 95. So what is the age of Ria’s Mother?**

A. 55

B. 35

C. 45

D. 40

A. 18.33 years

B. 12.5 years

C. 16.7 years

D. 13.33 years

E. 14.5 yearsAnswer –**D. 13.33 years**

**Explanation :**

Eight years ago, Ravi’s age = x

Eight years ago, Ravi’s Mother age = 5x

2(x+16) = 5x+16

2x+32 = 5x+16

x=16/3

Present age of Ravi = 16/3 + 8 = 13.33 years**The ratio of Arun’s and Varun’s ages is 4:5. If the difference between the present age of Varun and the age of Arun 5 years hence is 3 years, then what is the total of present ages of Arun and Varun?**

A. 73 years

B. 72 years

C. 75 years

D. 69 years

E. 68 yearsAnswer –**B. 72 years**

**Explanation :**

Arun’s age = x

Varun’s age = y

x/y = 4/5

y – (x + 5) = 3

y – x = 8

y = 8 + x

x/8 + x = 4/5

x = 32 years

y = 40 years.

x + y = 72 years.**The ages of Ashwini, Kavitha and Chitra together are 57 years. Kavitha is thrice as old as Ashwini and Chitra is 12 years older than Ashwini. Then, what is the ratio of respective age of Ashwini, Kavitha and Chitra is?**

A. 3 : 9 : 7

B. 3 : 9 : 2

C. 3 : 9 : 4

D. 3 : 9 : 5

E. 3 : 9 : 8Answer –**A. 3 : 9 : 7**

**Explanation:**

Ashwini’s age = X

Chitra’s age = x+12

Kavitha’s age = 3x

x + (x+12) + 3x = 57

=> 5x = 45

x = 9

Anushka’s age = 9

Kavitha’s age = 3x = 27

Chitra’s age = x+12 = 21; Ratio = 3:9:7**8 years ago, Arun’s age was 4/3 times that of Vinoth. 8 years hence, Arun’s age will be 6/5 times that of Vinoth. What is the present age of Arun?**

A. 20

B. 25

C. 30

D. 35

E. 40Answer –**E. 40**

**Explanation :**

Present age of Arun = x

Present age of Vinoth = y

x – 8 = 4/3 (y – 8)

x + 8 = 6/5 (y + 8)

3/4(x – 8) = y – 8

5/6(x + 8) = y + 8

y = 3/4 (x – 8) + 8 = 5/6 (x + 8) – 8

10 – 20/3 = 10/12 x – 9/12 x

10/3 = x/12

x = 40.**When Ramesh was born, his father was 32 years older than his brother and his mother was 25 years older than his sister. If Ramesh’s brother is 6 years older than Ramesh and his mother is 3 years younger than his father, how old was Ramesh’s sister when Ramesh was born?**
