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) 180/14 min past 10 | B) 180/11 min past 9 |

C) 148/7 min past 10 | D) 154/11 min past 9 |

Explanation:

At 9 o’clock, the hour hand is at 9 and the minutes hand is at 12, i.e., the two hands are 15 min. spaces apart.

So, the minute hand should gain = (30 - 15) minutes = 15 minutes

55 minutes will be gained in 60 min.

15 minutes spaces will be gained in ((60/55) x 15) min. = 180/11 min.

The hands will be in the same straight line but not together i.e.,in 180 degrees at 180/11 min. past 9.

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) 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) 36 minutes | B) 48 minutes |

C) 35 minutes | D) 60 minutes |

Explanation:

For 1 hour, 20 minutes is slower, then for

06 miuntes - 2 minutes is slower

30 minutes - 10 minutes

Actual time | false time

12 12

01 PM 12:40 PM (20 minutes slower)

02 PM 01:20 PM

03 PM 02:00 PM

So, when actual time is 3pm, the false time is 2 pm.

So, it loses 60 minutes when it shows 2 pm.
