Q 2 - The resent ages of A, B and C are in the ratio of 8:14:22 respectively. The resent ages of B, C and D are in the ratio of 21:33:44 respectively. Which of the following represents the ratio of the present ages of A, B, C and D respectively.

A - 12:21:33:44

B - 12:22:31:44

C - 12:21:36:44

D - Cannot be determined

### Explanation

```A : B : C = 8 : 14 : 22 = 12 : 21 : 33
B : C : D = 21 : 33 : 44

Therefore, A : B : C : D = 12 : 21 : 33 : 44```

Q 3 - One year ago the ratio of Yamini?s and Gamini?s ages was 6 : 7 respectively. Four years hence this ratio would become 7 : 8. How old is Gamini?

A - 35 years

B - 30 years

C - 31 years

D - 36 years

### Explanation

```Let one year ago the ages of Yamini and Gamini be 6x and 7x years respectively.

Therefore, present ages will be 6x + 1 and 7x + 1 years respectively.

Now four years hence,

(6x + 1 + 4) / (7x + 1 + 4)  = 7/8
Or, (6x + 5)  / (7x + 5) = 7/8
Or, 49x + 35 = 48x + 40
Or, X = 40 - 35 = 5

Hence Gamini's present age = 7x + 1  = 7*5 + 1 = 36 years```

Q 4 - Prabhakar is 15 years older than Navin and Navin is 25 years younger than Ashok. Which of the following represents the difference between the ages of Ashok and Prabhakar?

C - (40 + N) years

D - None of these

### Explanation

```According to question,

A = N + 25

A - P = (N + 25) - (N + 15) = 10 years```

Q 5 - What should be the present age of a man if the given condition is such as 15 year hence , a men will be 4 times as old as he was before the period of 15 year?

A - 10 years

B - 15 years

C - 20 years

D - 45 years

### Explanation

```Let man present age be x years.
His age 15 year ago = (x-15) years.  His age 15year hence = (x+15) years.
(x+15) = 4(x-15) ⇒ 3x= 45 ⇒ x = 45```

Q 6 - If the age of a mother is 3 times in the comparison of her daughter before the period of 10 year . 10 year later from the present date , the mother age would be 2 times of her daughter. In that situation what should be the age ratio of them at the present time?

A - 13:4

B - 9:2

C - 7:3

D - 5:2

### Explanation

```If the x year is the present age of her daughter.
Mother age 10 year ago = 3(x-10) = (3x-30) year
Present age of the mother = ( 3x-30+10) = (3x-20) year
After 10 year age of the mother = (3x-20 +10) = (3x-10) year
Son age after the period of 10 year = (x+10) year
∴  (3x-10) = 2(x+10) ⇒ x = 30
Mother present age = (3x-20) year = 70 years.
Daughter present age = 30 years.
Required ratio =  70: 30 = 7:3```

Q 7 - The product of Ram age 5 year ago with his age 7 years later is 28 . What should be the present age of mr. Ram ?

A - 4 years

B - 6 years

C - 7 years

D - 8 years

### Explanation

```If present age of ram is x years. then
(x-5)*(x+7) = 28 ⇒ x2 +2x-35 = 28 ⇒ x2+2x-63 =0
⇒ (x+9) (x-7) = 0 ⇒ x =7
∴ 7 years is the present age of  ram.```

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

### 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 - The sum of the ages of five girl born at the interval of 3 years each is 50 years. Find out the youngest girl age?

Required age = 4 yrs.```
