A) 45

B) 40

C) 35

D) 30

**Solution: **

Let the present age of P and Q be 3x and 4x respectively.

Ten years ago, P was half of Q's age

(3x-10)=1/2(4x-10)?6x-20=4x-10=> 2x=10=>x=5

Total of their present ages=3x+4x=7x=7×5=35

Ten years ago, P was half of Q's age

(3x-10)=1/2(4x-10)?6x-20=4x-10=> 2x=10=>x=5

Total of their present ages=3x+4x=7x=7×5=35

**Q6) The present ages of three persons in proportions 4 : 7 : 9. Eight years ago, the sum of their ages was 56. Find their present ages (in years). **

A) 8, 20, 28

B) 16, 28, 36

C) 20, 35, 45

D) None of these

**Solution: **

Let their present ages be 4x, 7x and 9x years respectively.

Then, (4x – 8) + (7x – 8) + (9x – 8) = 56

20x = 80

x = 4.

Their present ages are 4x = 16 years, 7x = 28 years and 9x = 36 years

respectively.

Then, (4x – 8) + (7x – 8) + (9x – 8) = 56

20x = 80

x = 4.

Their present ages are 4x = 16 years, 7x = 28 years and 9x = 36 years

respectively.

**Q7) When Rajesh was born, his father age was 29 years older than his Brother and his Mother was 25 years older than his Sister. If his Brother is 2 years elder than his Sister. After 6 years the average age of the family is 20. Then what is the age of Mother when Rajesh was born? **

A) 27

B) 28

C) 29

D) 30

**Solution: **

Sister = x; Brother = x+2; Father = 29+x+2; Mother = 25+x

Present age – 4x+58

After 6 years

4x+58+30 = 4x+88

4x+88 = 100

x = 3

Mothers age = 25+x = 28.

Present age – 4x+58

After 6 years

4x+58+30 = 4x+88

4x+88 = 100

x = 3

Mothers age = 25+x = 28.

**Q8) The sum of present ages of Ashok, Anil and Ajay is 75 years.If 5 years ago the ratio of their ages was 3 : 4 : 5, What is the present age of Anil? **

A) 26 Years

B) 25 Years

C) 32 Years

D) 65 Years

**Solution: **

Let 5 years age, the age of ashok, Anil and Ajay were 3x, 4x and 5x

years. Then, their present ages are ( 3x + 5), (4x + 5) abd ( 5x + 5) years.

Now, 3x +5 + 4x +5 + 5x + 5 = 75 => 12x = 60 x = 5

Hence, present age of Anil = 4x + 5 = 4 x 5 + 5 = 25 years.

years. Then, their present ages are ( 3x + 5), (4x + 5) abd ( 5x + 5) years.

Now, 3x +5 + 4x +5 + 5x + 5 = 75 => 12x = 60 x = 5

Hence, present age of Anil = 4x + 5 = 4 x 5 + 5 = 25 years.

**Q9) The ages of two persons differ by 16 years. 6 years ago, the elder one was 3 times as old as the younger one. What are their present ages of the elder person? **

A) 30

B) 25

C) 20

D) 15

**Solution: **

Let's take the present age of the elder person = x and the present age

of the younger person = x 16 (x 6) = 3 (x-16-6) => x 6 = 3x 66 => 2x = 60

=> x = 60/2 = 30

of the younger person = x 16 (x 6) = 3 (x-16-6) => x 6 = 3x 66 => 2x = 60

=> x = 60/2 = 30

**Q10) Mindy’s current age is 3 times that of her daughter, Cindy. 4 years ago, Mindy’s age was 4 times that of her daughter, what will be Cindy’s age 5 years from now? **

A) 17 Years

B) 21 Years

C) 27 Years

D) 15 Years

**Solution: **

Let Cindy’s current age be x. Then Mindy’s age is 3x.

According to the question,

3x-4=4(x-4)

Or, 3x-4=4x-16

Or, x=12.

Thus, 5 years from now, Cindy’s age will be 12+5=17years.

According to the question,

3x-4=4(x-4)

Or, 3x-4=4x-16

Or, x=12.

Thus, 5 years from now, Cindy’s age will be 12+5=17years.
