Question
At what time between 5:30 and 6 will the hands of a clock be at right angles?
Answer: Option B
The correct option is A 43 (7/11) min. past 5
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
40 min. spaces are gained in
(60/55×40) min=43 (7/11) min
Answer is 43 (7/11) min past 5
