- 1. A clock is set right at 5am the clock loses 16min in 24 hours. What will be the right time when the clock indicates 10am? On the 4th day?

A.10.30pm

B.11pm

C.10.45pm

D.11.15pm

Answer & Explanation

Answer: Option B

Explanation:Time from 5am. On a day to 10pm. on 4th day = 89 hours.

Now 23 hrs 44 min. of this clock = 24 hours of correct clock

365/15 hrs of this clock = 24 hours of correct clock

89 hrs of this clock = ( 24 * 15/356 * 89) hrs of correct clock

= 90 hrs of correct clock.

So, the correct time is 11pm.

- 2. A clock is started at noon. By 20 minutes pas 4, the hour hand turned through:

A.130°

B.155°

C.90°

D.110°

Answer & Explanation

Answer: Option A

Explanation:**Angle traced by hour hand in 12 hrs = 360°**

Angle traced by hour hand in 4 hrs 20 mins

i.e., 4(20/60) = 4(1/3)

= 13/3 hr

= 13/3 × (360/12) = 130°

Angle traced by hour hand in 4 hrs 20 mins

i.e., 4(20/60) = 4(1/3)

= 13/3 hr

= 13/3 × (360/12) = 130°

- 3. If a clock shows 4'O clock in the noon. Through how many degrees will the hour hand rotate when the clock shows 12'O clock in the night?

A.150°

B.240°

C.130°

D.170°

Answer & Explanation

Answer: Option B

Explanation:**Angle traced hour hand in 7 hours = 360°/12 × 8 = 120 × 2 = 240°**

- 4. The angle between the minute hand and the hour hand of a clock when the time is 6.30 is:

A.75°

B.120°

C.160°

D.115°

Answer & Explanation

Answer: Option A

Explanation:**The angle traced by hour hand in 6.30 hours = 6(30/60) = 6(1/2)**

=>(13/2) × (360/12) = 195°

The angle traced by minute hand in 45 minutes = (360/60) × 45 = 270°

Angle between hour and minute hand = 270° - 195° = 75°

=>(13/2) × (360/12) = 195°

The angle traced by minute hand in 45 minutes = (360/60) × 45 = 270°

Angle between hour and minute hand = 270° - 195° = 75°

- 5. What is the reflex angle between the hands of a clock at 4.30?

A.195°

B.70°

C.315°

D.150°

Answer & Explanation

Answer: Option C

Explanation:**Angle traced by hour hand in 4 hr 30 min = 4(1/2) = 9/2 hr**

= (360/12) × (9/2) = 15 × 9 = 135°

Angle traced by minute hand in 30 min = (360/60) × 30

= 180°

Reflex angle = 360° - [180° - 135°] = 360° - 145° = 315°

= (360/12) × (9/2) = 15 × 9 = 135°

Angle traced by minute hand in 30 min = (360/60) × 30

= 180°

Reflex angle = 360° - [180° - 135°] = 360° - 145° = 315°
