**The sum of ages of family members (both children and parents) is 360 years.The total ages of children and parents are in the ratio 2:1 and the ages of wife and husband are in the ratio 5:7.What will be the age of husband?**

A.65

B.75

C.72

D.70

Answer

Option (d) is correct

**Explanation-**

Sum of ages is 360 years.

The ratio of children and parents ages is 2:1.

Total age of parents = 360 x (1 / (2+1)) = 120 years

Ratio of wife and husband age is 5:7.

Therefore, the age of husband = 120 x (7 / (5+7)) = 70

Hence the age of husband is 70 years.

**The ratio between the present ages of A and B is 6:7. If B is 4 years old than A. What will be the ratio of the ages of A and B after 4 years?**

A.5 : 7

B.7 : 8

C.8 : 7

D.Data inadequate

Answer

Option (b) is correct

**Explanation –**

Let A’s age and B’s age be 6X years and 7X years respectively

Then, 7X – 6X = 4

X = 4

Required ratio = (6X + 4) : (7X + 4)

= (6×4)+4 : (7×4)+4

=28 : 32 = 7 : 8

**Sush was thrice as old as Poonam 6 years back. Sush will be 5/3 times as old as Poonam 6 years hence. How old is Poonam today?**

A.20

B.14

C.12

D.15

Answer

Option (c) is correct

**Explanation –**

Let Poonam age 6 years back = X.

Then, Sush age 6 years back = 3X.

Then, Poonam age 6 years later= X+6+6.

Then, Sush age 6 years later= 3X+6+6.

As given in question, 6 years later

(5/3) * (X + 6 + 6) = (3X + 6 + 6)

5(X+ 12) = 3(3X+ 12),

so X=6.

Poonam Age at present = (X+ 6) years = 12 years

**Present ages of Simmi and Anu are in the ratio of 5 : 4 respectively. Three years hence, the ratio of their ages will become 11 : 9 respectively, What is Anu’s present age in years?**

A.20

B.24

C.28

D.35

Answer

Option (b) is correct

**Explanation –**

Let the present ages of Simmi and Anu be 5x years and 4x years respectively

Then, [5X + 3] / [4X + 3] =11/9

Solving we get X=6

Anu’s present age = 4X = 24 years

**If 6 years are subtracted from the present age of Anuj and the remainder is divided by 18, then the present age of his grandson Gopal is obtained.If Gopal is 2 years younger to Mohan whose age is 5 years, then what is the age of Anuj?**

A.44

B.60

C.80

D.92

Answer

Option (b) is correct

**Explanation –**

Let Anuj’s age be X

Gopal is 2 years younger than Mohan, so Gopal is 3 years (i.e 5 – 2 = 3)

If 6 years are subtracted from Anuj’s age we get, X – 6.

As per the question, X – 6 should divided by 18 which will give Gokul’s age.

i.e. (X – 6) /18= 3

X-6 =3 x 18

x = 60
