A) 54 past 4 | B) (53 + 7/11) past 4 |

C) (54 + 8/11) past 4 | D) (54 + 6/11) past 4 |

Explanation:

4 o'clock, the hands of the watch are 20 min. spaces apart.

To be in opposite directions, they must be 30 min. spaces apart.

Minute hand will have to gain 50 min. spaces.

55 min. spaces are gained in 60 min

50 min. spaces are gained in min. or

Required time = min. past 4.

A) 10 : 27 : 41 AM | B) 8 : 51 : 04 AM |

C) 9 : 45 : 15 PM | D) 10 : 23 : 20 PM |

Explanation:

The watch gains 5 seconds in 3 minutes = 100 seconds in 1 hour.

From 8 AM to 10 PM on the same day, time passed is 14 hours.

In 14 hours, the watch would have gained 1400 seconds or 23 minutes 20 seconds.

So, when the correct time is 10 PM, the watch would show 10 : 23 : 20 PM

A) 90 degrees | B) 85 degrees |

C) 60 degrees | D) 45 degrees |

A) 16 deg | B) 80 deg |

C) 88 deg | D) 94 deg |

Explanation:

In one hour, the minute hand gains 330° over the hour hand. i.e., 60 minute, the minute hand gains 330° over the hour hand.

∴ In 16 minutes, the minute hand gain over the hour hand by

A) 66 sec | B) 55 sec |

C) 36 sec | D) 24 sec |

Explanation:

For ticking 6 times, there are 5 intervals.

Each interval has time duration of 30/5 = 6 secs

At 12 o'clock, there are 11 intervals,

so total time for 11 intervals = 11 x 6 = 66 secs.

A) 3:15 2/8 | B) 3:49 |

C) 3:49 1/11 | D) 3:51 |

Explanation:

On straight line means 180 degree angle.

180 = 11/2 min – 30 hrs

180 = 11/2 m – 30 × 3

180 = 11/2 m – 90

(180 + 90) 2 = 11 m

m = 540/11 = 49 1/11 minutes.
