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.

Let the present age's of mother be 'M' and that of her son be 'S'.

According to the given data in the question,

M - 5 = 3(S - 5)

F - 3S = -10 ...............(1)

Then given ,

M + 5 : S + 5 = 11 : 5

=> 5M - 11S = 30 ..............(2)

From (1) & (2), we get

S = 20

Then by substituting S = 20 in (1) or (2), we get

M = 50.

Hence, the present age of mother is **M = 50 years.**

A) 32 | B) 33 |

C) 34 | D) 35 |

Explanation:

Given S = 17 yrs

A = 16 yrs

B = 12 yrs

Average = 17 + 16 + 12/3 = 15 yrs

Given if Aslam added to them, their average increases by 5

=> Average of 4 members = 20

Let the age of Aslam be 'x'

Then,

17 + 16 + 12 + x /4 = 20

=> x = 80 - 45

=> x = 35.

Hence, the age of Aslam is **35 yrs.**

A) 8, 72 yrs | B) 16, 65 yrs |

C) 12, 84 yrs | D) 10, 60 yrs |

Explanation:

Let the present ages be K,M

Given K/M = 4/5

**5K - 4M = 0 ......(1)**

Also given that,

M - (K + 5) = 3

**M - K = 8 .........(2)**

Then, by solving (1) & (2)

**M = 40 yrs** and **K = 32 yrs**

Hence, Total of ages = **40 + 32 = 72 yrs**

Difference of ages = **40 - 32 = 8 yrs.**

A) 12 | B) 14 |

C) 22 | D) 10 |

Explanation:

Let Rajeev's present age be x years.

Rajeev's age after 15 years = (x + 15) years.

Rajeev's age 5 years back = (x - 5) years

Then ATQ,

x + 15 = 5 (x - 5)

x + 15 = 5x - 25

=> x = 10

Hence, Rajeev's present age = x = 10 years.

A) 28.5 yrs | B) 29.5 yrs |

C) 30.5 yrs | D) 27 yrs |

Explanation:

According to the given data,

(V + R)/2 = 24

Now, after joining of Veerender,

V + R + D)/3 = 25.5

Hence, Veerender Age = 3(25.5) - 2(24) = 76.5 - 48 = 28.5 years.

A) 2 | B) 3 |

C) 4 | D) 5 |

Explanation:

According to the given data,

**P + Q = 41 ......(1)**

R - 1 = P + 2

**R = P + 3**

and

P + 4 = Q - 1

**=> Q = P + 5 ....(2)**

From (1)&(2)

P = 18

Q = 18 + 5 = 23

R = 18 + 3 = 21

**=> P/S = 3/4**

**=> S = 4/3 x 18 = 24**

Required Difference **= S - R = 24 - 21 = 3.**

A) 6 yrs | B) 4 yrs |

C) 8 yrs | D) 2 yrs |

Explanation:

Let the present age of Deepa = 5p

Let the present age of Hyma = 6p

After four years their ratio = 6 : 7

=> $\frac{\mathbf{5}\mathbf{p}\mathbf{}\mathbf{+}\mathbf{}\mathbf{4}}{\mathbf{6}\mathbf{p}\mathbf{}\mathbf{+}\mathbf{}\mathbf{4}}\mathbf{}\mathbf{=}\mathbf{}\frac{\mathbf{6}}{\mathbf{7}}$

=> 35p + 28 = 36p + 24

=> p = 4

**Therefore,** the difference between their ages** = 24 - 20 = 4 years.**

A) 25 | B) 30 |

C) 35 | D) 40 |

Explanation:

Present age of Sony = 24 + 4 = 28 years

After 5 years Renuka's age = **7×5 + 5 = 40 years**
