To the 6

Explanation:

Starting with the top left clockface and working clockwise around the others, the sum of the numbers pointed to by the 2 hands starts at 3 and increases by 2 each time.

A) 1 10/11 minutes past 2 | B) 1 10/11 minutes past 3 |

C) 1 11/10 minutes past 3 | D) 11 10/11 minutes past 2 |

Explanation:

Since, in one hour, two hands of a clock coincide only once, so, there will be value.

Required time minutes past H.

Here H - initial position of hour hand = 2 (since 2 O'clock)

A° = Required angle = 0° (Since it coincides)

minutes past 2

=> minutes past 2

A) 155 degrees | B) 175 degrees |

C) 205 degrees | D) 215 degrees |

Explanation:

The total angle traced by the hour hand is the angle traced in 7 hours and 10 minutes.

We know that the angle traced by the hour hand in one hour is 30º and in one minute is 1/2º.

Therefore, (30º x 7) + (10 x 1/2º) = 215º is the angle traced by the hour hand.

A) 541 times | B) 540 times |

C) 450 times | D) 275 times |

Explanation:

There are 60 minutes in an hour.

In ¾ of an hour there are (60 × ¾) minutes = 45 minutes.

In ¾ of an hour there are (60 × 45) seconds = 2700 seconds.

Siren sounds for every 5 seconds.

In 2700 seconds = 540 times.

The count start after the first sound, the Siren will sound 541 times in ¾ of an hour.

A) 5 degrees | B) 10 degrees |

C) 15 degrees | D) 25 degrees |

Explanation:

Since at 4 : 20 the minute hand will be at 4 and the angle between them will be same as the distance covered in degree by the hour hand in 20 minutes.

Required angle = distance of hour hand = speed × time = × 20 =10 degrees.
