# Puzzles Questions

A) 20 | B) 22 |

C) 24 | D) 48 |

Explanation:

The hands of a clock point in opposite directions (in the same straight line) 11 times in every 12 hours. (Because between 5 and 7 they point in opposite directions at 6 o'clcok only).

So, in a day, the hands point in the opposite directions 22 times.

A) 145 | B) 150 |

C) 155 | D) 160 |

Explanation:

Angle traced by hour hand in 12 hrs = 360º.

Angle traced by hour hand in 5 hrs 10 min. *i.e., 31/6 hrs *= ${\left(\frac{360}{12}*\frac{31}{6}\right)}^{\xb0}$= 155º

A) 062 | B) 602 |

C) 042 | D) 204 |

Explanation:

From all the hints given,

only **042** satisfies and it unlocks the key.

A) 2 p.m. on Tuesday | B) 2 p.m. on Wednesday |

C) 3 p.m. on Thursday | D) 1 p.m. on Friday |

Explanation:

Time from 12 p.m. on Monday to 2 p.m. on the following Monday = 7 days 2 hours = 170 hours.

The Watch gains $\left(2+4\frac{4}{5}\right)$ min. or $\frac{34}{5}$ min.in 170 hrs.

Now, $\frac{34}{5}$min.are gained in 170 hrs.

2 min.are gained in$\left(170*\frac{5}{34}*2\right)$ hrs=50 hrs

Watch is correct 2 days 2 hrs. after 12 p.m. on Monday *i.e.,* it will be correct at 2 p.m. on Wednesday

A) 3 | B) 4 |

C) 1 | D) 2 |

Explanation:

4 eyes.

Here in the question, it is asked how many Eyes We have so that means here the person who has asked the question is also including the person who is suppose to give the answer. In a clear understanding, the Conversation is happening between 2 people 1st who asked the question and 2nd to whom it has been asked, which means there are 4 eyes.

A) 120 degrees | B) 125 degrees |

C) 130 degrees | D) 135 degrees |

Explanation:

Angle traced by hour hand in 12 hrs. = 360º.

Angle traced by it in 11/3 hrs= ${\left(\frac{360}{12}*\frac{11}{3}\right)}^{\xb0}$=${110}^{\xb0}$

Angle traced by minute hand in 60 min. = 360º.

Angle traced by it in 40 min. =(360/60*40)${\xb0}^{}$=240${\xb0}^{}$

Required angle (240 - 110)º = 130º.
