Ages Quiz 1

Explanation :

Let Ajay Devgan's present age be x years .

Then, According to question

(38 - x) = x

x= 19.

Ajay Devgan's age 5 years back = (19 - 5) = 14 years

Explanation :

Let number of Males= x  , Let number of females= y

Total numbers of members in the crew= x + y

(x + y) \times 15.8 = 16.4x + 15.4y

0.6x = 0.4y

\frac{x}{y} = \frac{0.4}{0.6} = \frac{2}{3}

Ratio of males and females in the cast is 2:3

Explanation :

Let the mother's present age be x years.

Then, the person's present age = \frac{2}{5} x years.

  \frac{2x}{5}+8=\frac{1}{2}(x+8)

2(2x + 40) = 5(x + 8)

=> x = 40.

Explanation :

Let the Father be x years when he died

Average Age 10 years ago be A

Total Age 10 years ago = 6*A

Total Age after 10 years(Just before father's Death) = 6A + 6*10 = 6A + 60

Father Died and Baby was born => the Total number of people in the family is Same (6)

Baby born today so age of baby = 0

\frac{(6A +60 - x)}{6} = \frac{6A}{6}

=> A + 10 -\frac{x}{6} = A

=> \frac{x}{6} = 10

=> x = 60

Therefore we can conclude that the father was 60 years old when he died.

Explanation :

Let Megan Fox's age be x.

Therefore, Gal Gadot's age becomes x+2.

After 6 years their ages become x+6,x+8.

Now,

Making equations

x+6+x+8=7(x+x+2)

2x+14=14x+14

14x-2x=0

x=0

Therefore, Gal Gadot's age becomes 2 years

Explanation :

Denzel Washington’s age = 3A and Brad Pitt’s age = 5A

\frac{3A+9}{(5A+9} = \frac{3}{4}

=> 4 (3A + 9) = 3 (5A + 9)

=> A = 3

Therefore, Brad Pitt’s age = 15 years.

Explanation :

Let the Present age of Henry Cavill is x

Ben Affleck's age = 5-2 = 3

x-\frac{6}{18} = 3

x-6 = 54

x = 60

Henry Cavill's present age = 60 years

Explanation :

Let Dan Carter's age at the time of his marriage = X years

Then from given data

=> X + 8 = 6/5 X

X = 40.

Since got married 8 years ago, his present age  = 48

His sister is 10 years younger = 48 - 10 = 38 years

Explanation :

Let the present ages of Ranveer Singh and Ranbir Kapoor be 'x' and 'y' years respectively.

Eight years ago,

Ranveer Singh’s age = x-8

Ranbir Kapoor’s age =y-8

x-8 = \frac{4}{3} \times(y-8)

x=\frac{4}{3}y-\frac{32}{3}+8

Eight years hence

Ranveer Singh’s age = x+8

Ranbir Kapoor’s age = y +8

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

x=\frac{6}{5}y+\frac{48}{5}–8

equating both x value

\frac{4}{3}y-\frac{32}{3}+8 = \frac{6}{5}y+\frac{48}{5}–8

\frac{2}{15}y = \frac{304}{15}-16

y = 32

therefore x = 40

Explanation :

Let the present ages of Christian Bale, Ben Affleck and Adam West be k, l and m respectively.

k/l = 5/x ------ (1)

k = m - 18 ------ (2)

m + 9 = 47 ------ (3)

k - l = m ----- (4)

From 3,

=> m = 47 - 9 = 38 years

From 2,

=> k = 38 -18 = 20 years

From 1

=> \frac{20}{l} = \frac{5}{x}

=> l = 4x

And From 4,

=> 4x - 20 = 38

=> 4x = 58

=> x = 14.5
