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

A - 5 min. past 7

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

C - 5 $\frac{2}{11}$ min. past 7

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

### Explanation

$\frac{60}{55}$ × 5 = 5$\frac{5}{11}$ min. past 7

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 - Number of hours and minutes from 6.20 am to 9.30 pm on the same day is

A - 15 hours 10 mins

B - 15 hours 20 mins

C - 15 hours 05 minutes

A - Once

B - Twice

C - Thrice

D - None of these

### Explanation Q 6 - At what time between 9 and 10 Oclock will the hands of a clock be in the same straight line but not together?

A - 15$\frac{4}{11}$ min past 9

B - 16$\frac{4}{11}$ min past 9

C - 17$\frac{4}{11}$ min past 9

D - 18$\frac{4}{11}$ min past 9

### Explanation

$\frac{5n-30}{11}$ × 12 min past n,

Given n = 9, $\frac{45-30}{11}$ × 12 = 16$\frac{4}{11}$ min past 9

Q 7 - At what time between 3.30 and 4 Oclock will the hands of a clock be at right angle?

A - 32$\frac{8}{11}$ minute past 3

B - 45$\frac{8}{11}$ minute past 3

C - 35$\frac{8}{11}$ minute past 3

D - 32$\frac{5}{11}$ minute past 3 ### Explanation

It is clear from the figure that minute hand has to travel through 30 minute space.

Therefore 30 minute space can be gained in $\frac{12}{11}$ × 30 = 32 $\frac{8}{11}$ minute past 3

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?

A - 8.20 am

C - 8.40 am

D - 8.50 am

### Explanation

Rams reaching time = 8.10 am

D - 70o

### Explanation

Required angle = 240 – 170 = 70o

A - 7$\frac{5}{11}$ min past 1

B - 8$\frac{5}{11}$ min past 1

C - 6$\frac{5}{11}$ min past 1

D - 5$\frac{5}{11}$ min past 1

$\frac{60n}{11} = \frac{60 \times 1}{11} = 5 \frac{5}{11}$
