Solution:

QUESTION: 2

The average age of a man and his two twin sons is 30 years. The ratio of the ages of father and one of his sons is 5:2. What is the father’s age

Solution:
Let father's age be M and age of twins be 2x

(M + 2x)/3 = 30

M + 2x = 90------------(1)

M/x = 5/2

2M = 5x---------------(2)

Multiply (1) with 2

We get, 2M + 4x = 180--------------(3)

Putting (2) in (3)

5x+4x = 180 => 9x = 180x = 20. [his children are twins so 2x = 40]Since M + 2x = 90M = 90 -40 = 50years

(M + 2x)/3 = 30

M + 2x = 90------------(1)

M/x = 5/2

2M = 5x---------------(2)

Multiply (1) with 2

We get, 2M + 4x = 180--------------(3)

Putting (2) in (3)

5x+4x = 180 => 9x = 180x = 20. [his children are twins so 2x = 40]Since M + 2x = 90M = 90 -40 = 50years

QUESTION: 3

Two years ago the ratio of ages of A and B was 5:7. Two years hence the ratio of their ages will be 7:9. What is the present age of B.

Solution:
Let x,y be present ages of A,B.

x-2/y-2=5/7 implies 7x-5y=4 -(1)

x+2/y+2=7/9 implies 9x-7y=-4. (2)

(1) * 7 - (2) * 5 gives x=12

substitute and get y which would be 16

x-2/y-2=5/7 implies 7x-5y=4 -(1)

x+2/y+2=7/9 implies 9x-7y=-4. (2)

(1) * 7 - (2) * 5 gives x=12

substitute and get y which would be 16

QUESTION: 9

At present Tarun is twice the age of Vishal and half of Tanvi’s age. After four years Tarun will be 1.5 times Vishal’s age and Tanvi will be 2.5 times Vishal’s age. What is Tanvi’s present age?

Solution:

Vishal's present age = x years

Tarun's present age = 2x years

Tanvi's present age = 4x years

After 4 years.

Tarun's age = 1.5 * Vishal's age

=> 2x + 4 = 1.5(x+4)

=> 2x - 1.5x = 2

=>0.5x = 2 => x = 2/0.5 = 4

Tanvi's present age = 16 years.

QUESTION: 10

On Teacher’s Day, 4800 sweets were to be equally distributed among a certain number of children. But on that particular day 100 children were absent. Hence, each child got four sweets extra. How many children were originally supposed to be there?

Solution:

Let the original number of children be x.

∴ 4800/x-100 - 4800/x = 4

=> 4800((x-x+100)/(x(x-100))) = 4

=> x(x-100) = 1200 * 100

=> x(x-100) = 400(400-100)

=> x = 400

QUESTION: 11

The ratio between the present ages of P and Q is 6:7. If Q is four years older than P, what will be the ratio of the ages of P and Q after 4 years?

Solution:
P:Q = 6:7 i.e P/Q = 6/7 => 7P = 6Q--------1

Given that Q = P + 4 (put in 1)

7P = 6(P + 4)

So, P = 4 and Q = P+4 i.e 8years

After 4 years, P+4 i.e 4+4= 8yrs

And Q = 8 +4 = 12years

The ratio we get is 2:3

None of the above mentioned options are correct so option 'E' is correct

Given that Q = P + 4 (put in 1)

7P = 6(P + 4)

So, P = 4 and Q = P+4 i.e 8years

After 4 years, P+4 i.e 4+4= 8yrs

And Q = 8 +4 = 12years

The ratio we get is 2:3

None of the above mentioned options are correct so option 'E' is correct
