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) 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.

A) 12 p.m. on Wednesday | B) 2 p.m. on Thursday |

C) 3 p.m. on Thursday | D) 2 p.m. on Wednesday |

Explanation:

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

= 170 hours.

The watch gains = (2 + 4 x 4/5) min

= 34/5 min. in 170 hrs.

Now, 34/5 min are gained in 170 hrs.

Then, 2 min are gained in (170 x 5/34 x 2) hrs.

Watch is correct after 2 days 2 hrs after 12 p.m. on Tuesday, i.e., it will be correct at 2 p.m. on Thursday.

A) Option A | B) Option B |

C) Option C | D) Option D |

Explanation:

At 3 o'clock, the minute hand is 15 min. spaces apart from the hour hand.

To be coincident, it must gain 15 min. spaces.

55 min. are gained in 60 min.

Then 15 min spaces are gained in = min.

The hands are coincident at min. past 3 o'clock.

A) 144º | B) 168º |

C) 180º | D) 150º |

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 min. or min. in 170 hrs.

Now, min. are gained in 170 hrs.

2 min are gained in 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.
