Q 1 - A clock is set right at 6 p.m. the clock loses 16 min. In 24 hrs. What will be true time if the clock indicates 11p.m on 4^th day?

Answer : A

Explanation

$\left ( 24 \times \frac{15}{356} \times 89 \right )$ hrs = 90 hrs of correct clock, correct time will be mid night.

Q 2 - If a clock started at noon, then the angle turned by hour hand at 3.45 pm is?

A - 104$\frac{1}{2}^{\circ}$

B - 117$\frac{1}{2}^{\circ}$

C - 97$\frac{1}{2}^{\circ}$

D - 112$\frac{1}{2}^{\circ}$

Answer : D

Explanation

3 + $\frac{45}{6}$ = (3 + $\frac{3}{4}$)×30 = 112$\frac{1}{2}^{\circ}$

Q 3 - At 3.40, the hour hand and minute of a clock forms an angle of?

Answer : C

Explanation

Angle turned in 12 hrs = 360^o

Angle turned in 11/3 hrs = ( $\frac{360}{12}$ × $\frac{11}{3}$) = 110^o

Angle turned by minute hand in 60 min = 360^o

Angle turned by minute hand in 40 min = ($\frac{360}{60}$ × 40) = 240^o

Required angle = 240 - 110 = 130^o

Q 4 - What is the angle between two hands of a clock at 7.15?

A - 35$\frac{1}{2}^{\circ}$

B - 36$\frac{1}{2}^{\circ}$

C - 37$\frac{1}{2}^{\circ}$

D - 38$\frac{1}{2}^{\circ}$

Answer : C

Explanation

$\frac{360}{12}$ × $\frac{7}{4}$ = $\frac{210}{4}$, and $\frac{360}{60}$ × 15 = 90

Required angle = 90 - $\frac{210}{4}$ = 37$\frac{1}{2}^{\circ}$

Q 5 - If two hands are at 15^o, they are 15 min space apart. It happens how many times in every 1 hour?

Answer : C

Explanation

Q 6 - In the morning 6 and 7 O`clock, what should be a particular time to make right angle?

A - 48$\frac{2}{11}$ min past 6 and 16$\frac{3}{11}$ min past 6

B - 49$\frac{1}{11}$ min past 6 and 16$\frac{4}{11}$ min past 6

C - 49$\frac{2}{11}$ min past 6 and 16$\frac{3}{11}$ min past 6

D - 49$\frac{3}{11}$ min past 6 and 16$\frac{4}{11}$ min past 6

Answer : B

Explanation

(5n ± 15) × $\frac{12}{11}$ min past 6, here n = 6

Therefore 49$\frac{1}{11}$ min past 6 and 16$\frac{4}{11}$ min past 6

Q 7 - Calculate the minute and hour from 8.15 am to 10.20 pm on the same day?

Answer : C

Explanation

total hour = 10.20 - 8.15 = 2.05

= 12.00 + 2.05 = 14 hrs 05min.

Q 8 - We decided to go a place at 30 min before 8.40 a.m, Ram found himself 40 min earlier than Hari who is 20 min late. Then what was the perfect time?

Answer : B

Explanation

Ram`s reaching time = 8.10 am

Hari found Ram at 45 min earlier = 8.50 am

The perfect time = 8.30 am

Q 9 - The minute hand of a clock overtakes the hour hand at an interval of 70 min of the correct time. How much time in a day does the clock gain or loss?

A - $\frac{7200}{77}$ min gain

B - $\frac{7300}{77}$ min loss

C - $\frac{7200}{77}$ min loss

D - $\frac{7300}{77}$ min gain

Answer : C

Explanation

$\left ( \frac{720}{11} - x \right ) \times\left ( \frac{60 \times 24}{x} \right )$ min

$\left ( \frac{720}{11} - 70 \right ) \times\left ( \frac{60 \times 24}{70} \right )$ min = -$\frac{7200}{77}$ min(loss)

Q 10 - At what time between 7 O`clock and 8 O`clock will the hands of a clock be in same straight line but not together?

A - 6$\frac{5}{11}$ min past 7

B - 5$\frac{5}{11}$ min past 7

C - 4$\frac{5}{11}$ min past 7

D - 3$\frac{5}{11}$ min past 7

Answer : B

Explanation

$\frac{\left ( 5n - 30 \right ) \times 12}{11}$ min past n(n>6) here n = 7 so, 5$\frac{5}{11}$ min past 7 is correct.
