# Clock puzzles Questions

A) 137.5 degrees | B) 222.5 degrees |

C) 192.5 degrees | D) 330 degrees |

Explanation:

Apply the formula for finding the angle:

Angle=(30h-(11/2)m( where m stands for minutes and h stands for hours)

Hence, 30x11 - 11/2x35 = 330 - 192.5 = 137.5 degrees

The reflex angle = 360 - 192.5 degree = 222.5 degrees.

A) 57 days | B) 58 days |

C) 60 days | D) 61 days |

Explanation:

In this problem , it has considered that 65 mins = 1hr

So mins has increased by 5 mins so multiply 5 x 24 = 120 mins extra ,

That is now per day it adds 2hr extra, so divide 1440/26 = 59.384 days =~ 60 days.

A) 26 min | B) 24 min |

C) 22 min | D) 20 min |

Explanation:

Let the required number of minutes = M

Total minutes between 3o'clock and 6o' clock = 180 minutes

M + 50 + 4M = 180

5M + 50 = 180

5M = 130

M = 26 minutes.

A) 155 degrees | B) 175 degrees |

C) 205 degrees | D) 215 degrees |

Explanation:

The total angle traced by the hour hand is the angle traced in 7 hours and 10 minutes.

We know that the angle traced by the hour hand in one hour is 30º and in one minute is 1/2º.

Therefore, (30º x 7) + (10 x 1/2º) = 215º is the angle traced by the hour hand.

A) 34.76 years | B) 32.48 years |

C) 33.31 years | D) 31.68 years |

Explanation:

We know that 1 year = 365.25 days

1 day = 24 hours

1 hour = 60 minutes

1 minute = 60 seconds

**=> 1 Year = 365.25 x 24 x 60 x 60 Seconds**

But 1 billion seconds = ?

1 Year = 365.25 x 24 x 60 x 60 Seconds

** ? = 1000000000 Seconds**

**$\mathbf{?}\mathbf{}\mathbf{=}\mathbf{}\frac{\mathbf{1000000000}}{\mathbf{365}\mathbf{.}\mathbf{25}\mathbf{}\mathbf{x}\mathbf{}\mathbf{24}\mathbf{}\mathbf{x}\mathbf{}\mathbf{60}\mathbf{}\mathbf{x}\mathbf{}\mathbf{60}}\mathbf{}\mathbf{years}$ = 31. 68 years.**
