A) 48 min. past 12. | B) 46 min. past 12. |

C) 45 min. past 12. | D) 47 min. past 12. |

Explanation:

Time from 8 a.m. on a day to 1 p.m. on the following day = 29 hours.

24 hours 10 min. of this clock = 24 hours of the correct clock.

hrs of this clock = 24 hours of the correct clock.

29 hours of this clock = hrs of the correct clock

= 28 hrs 48 min of the correct clock.

Therefore, the correct time is 28 hrs 48 min. after 8 a.m.

This is 48 min. past 12.

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 |

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 |
