Question : 68 of 200

Marks: +1, -0

At what time between 10 am and 11 am the angle between hands of a clock is

162 1°/2

Solution:

Angle between the hands of a clock is

62{1°/2}

θ=|30 H -\;{11}/{2} m |

162 \;{1^{∘}}/{2}=∣ 30(10)-\;{11}/{2} m

\;{325}/{2}=|300-\;{11}/{2} m |

300-\;{325}/{2}=\;{11}/{2} m

\;{600-325}/{2}=\;{11}/{2} m

\;{11}/{2} m =\;{275}/{2}

m=25

∴ The time is 10:25 am
