Let Rama's age 8 years ago be x years and mother's age 8 years ago be 5x

years

Hence, present age of Rama = years

A) 27, 9, 21 | B) 9, 21, 27 |

C) 21, 27, 9 | D) 9, 27, 21 |

Explanation:

Let Anushka age = X

Charu latha 12 yrs older than Anushka so Charu latha age = x+12

Kajal is thrice as old as Anushka so Kajal age = 3x

The ages of Anushka, Kajal and Charu latha together are 57 years

i.e x + (x+12) + 3x = 57

=> 5x = 45

:- x = 9

Anushka age = 9

Kajal age = 3x = 27

Charu latha age = x+12 = 21

A) 40 | B) 50 |

C) 60 | D) 70 |

Explanation:

Sony and her brother's age sum is 31

Let Sony's mother's age be 'x'.

Now the conditions given for both of their ages related to their mom is

1/5(x-15) + 3/5(x-10) = 31

x-15 + 3x-30 = 155

4x-45 = 155

4x = 200

x = 50

So, Mother's age = 50.

Cross verification : 15 years ago age = 35 => Sony age = 7

10 years ago age = 40 => bro age = 24

Sum = 24 + 7 = 31.

A) 50 yrs | B) 60 yrs |

C) 70 yrs | D) 65 yrs |

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

(6A +60 - x)/6 = 6A/6

=> A + 10 -(x/6) = A

=> x/6 = 10

=> x = 60

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

A) 5 | B) 10 |

C) 15 | D) 8 |

Explanation:

Raj Tarun's age = 0 when he was born.

Then, given his brother is 6 years old.

Then his father is 6 + 32 = 38 when Raj Tarun was born

And his mother is 3 years yonger than his father => so his mother was 35 years old when Raj Tarun was born

and his sister is 25 year younger than his mother

so Raj Tarun's sister was 10 years old when Raj Tarun was born.

A) 6 years | B) 4 years |

C) 7 years | D) None |

Explanation:

As given Kapil's 8th birthday was celebrated 2 years ago,

Kapil’s present age = 8 + 2 = 10 years.

Father's age is twice of Kapil’s age after 10 years.

=> F + 10 = 2 (K + 10) = 2 (10+ 10)

F = 30years,

Avanthi's age =1/6(F) = 30/6 = 5 years.
