A clock is started at noon. By 10 minutes past 5, the hour hand has turned through `145o` (b) `150o` (c) `155o` (d) `160o`

If a clock started at noon, then the angle turned by hour hand at 3.45 PM is

Equation of the hour hand at 4 O' clock is

Equation of the hour hand at 4 O' clock is

The angle between the minute hand and the hour hand of a clock when the time is 4.20, is 0o(b)10o(c)5o(d)20o

In an accurate clock,in a period of 2 hours 20 minutes the minute hand will move over 140o (b) 320 (c) 520o (d) 840o

At 3.40, the hour hand and the minute hand of a clock form an angle of 120o (b) 125o (c) 130o (d) 135o

At what time between 8 and 9 o'clock will the minute hand and the hour hand are perpendicular to each other ?

In Fig. 10.88, A P B is a tangent to a circle with centre O at point P . If /_Q P B=50o , then the measure of /_P O Q is (FIGURE) 100o (b) 120o (c) 140o (d) 150o

A clock gains 5 minutes in one hour. Therefore,the angle traversed by the minute hand in 1 hour is 360o (b) 390o(c)390.50 (d) None of these
