Explanation:

The alphabetical value of the letters in the left hand column follows through the sequence of Prime Numbers, with the letters in the right hand column representing the corresponding reverse alphabetical values. So,

M = Reverse of M = N.

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) 8 | B) 24 |

C) 16 | D) 4 |
