1. | At what time between 5.30 and 6 will the hands of a clock be at right angles? |
||||||||||||||||||||||
Answer: Option B Explanation: At 5 o'clock, the hands are 25 min. spaces apart. To be at right angles and that too between 5.30 and 6, the minute hand has to gain (25 + 15) = 40 min. spaces. 55 min. spaces are gained in 60 min.
