A - Friday

B - Saturday

C - Tuesday

D - Wednesday

### Explanation

$\frac{54}{5}$ in 180 hrs

5 min = 180 × $\frac{5}{54}$ = 83 hrs 20 min = 3 days 11 hrs and 20 min.

Its answer is correct at 20 min. past 6 pm on Wednesday.

Q 2 - An accurate clock shows 8 Oclock in the morning. Through how many degrees will the hour hand rotate when the clock shows 2 Oclock in the afternoon?

A - 144o

B - 150o

C - 168o

D - 180o

### Explanation

Angle traced by hour hand in 6 hours = $\frac{360}{12}$ × 6 = 180o

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

A - 120o

B - 125o

C - 130o

D - 135o

### Explanation

Angle turned in 12 hrs = 360o

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

Angle turned by minute hand in 60 min = 360o

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

Required angle = 240 - 110 = 130o

Q 4 - A clock is started at noon by 15 min past 5, the hour hand has turned through?

A - 157$\frac{2}{4}$

B - 160$\frac{2}{4}$

C - 159$\frac{2}{4}$

D - 161$\frac{2}{4}$

### Explanation

$\frac{360}{12}$ × $\frac{21}{4}$ = 157$\frac{2}{4}$

Q 5 - A watch which gains uniformly is 2 minutes slow at noon on Monday and 4 min 48 sec fast at 2.40 pm on the following day. At what time it was correct?

A - 2 pm on Tuesday

B - 2 pm on Wednesday

C - 3 pm on Thursday

D - 1 pm on Friday

### Explanation

From 12 noon to 2 pm on the following day

There are 7 day and 2 hours = 170 hours

Now watch gains 2 + 4$\frac{4}{5}$ = $\frac{34}{5}$ min in 170 hrs

It will gain 2 min $\frac{170 \times 5}{34}$ × 12 = 50 hrs = 2 days 2 hrs.

Q 6 - At what time between 4 and 3 Oclock will the hands of a clock point in opposite direction?

A - $\frac{549}{11}$ min past 4

B - 601 min past 4

C - $\frac{600}{11}$ min past 4

D - 602 min past 4

### Explanation

(5n + 30 )×$\frac{12}{11}$, n = 4

$\frac{50 \times 12}{11}$ min. past 4 = $\frac{600}{11}$

Q 7 - How much time does a clock gain if it coincide per 62 min in a day?

A - 80$\frac{2}{341}$

B - 81$\frac{2}{341}$

C - 82$\frac{2}{341}$

D - 83$\frac{2}{341}$

### Explanation

($\frac{720}{11}$ - x) × ($\frac{60 × 24}{x}$); given x = 62 then 80$\frac{2}{341}$

Q 8 - Ram takes 15 minutes to reach Madhus house, by walking. while he takes only 8 min to reach Madhus house by driving a vehicle. What is the difference of separation of time?
