Question

# 24. After 9 O'clock a 9 pm and 10 pm will the ter 9 o'clock at what time between 9 pm and 10 pm hour and minute hands of a clock point in opposite directions ? (1) 15 min past 9 (2) 16 min past 9 (3) 16 min past 9 (4) 17min past 9 11 no

Solution 24. (3) At 9 o'clock, the min hand is
9 x 5 = 45 min spaces behind the hour hand.
Therefore, the minute hand will have to gain
45 - 30 = 15 min spaces over the hour hand.
Gain of 55 min spaces equals 60 min.
... Gain of 15 min spaces equals
x 15 . 180 = 164

Therefore, hour and minute hands of a clock
point in opposite directions after 9 O'clock at
16 min past 9.
