Required angle 270 - 202.5 = 67.5o

Q 6 - In which particular time between 4 and 5 O`clock will the hands of a clock coincide together?

A - 20$\frac{9}{11}$

B - 21$\frac{9}{11}$

C - 22$\frac{9}{11}$

D - 23$\frac{9}{11}$

Answer : B

Explanation

Clock Coincide Together

There are 20 min space apart so, $\frac{60}{55}$ × 20 = 21 $\frac{9}{11}$

Q 7 - How many times the hands of a clock points towards each other in 24 hours?

A - 20

B - 21

C - 22

D - 23

Answer : C

Explanation

In general its 11 times points towards each other in 12 hours then in 24 hrs it is double i.e 22 times.

Answer : C

Explanation

$\frac{360}{12} \times \frac{117}{12} = 292\frac{5}{12}$

$\frac{360}{60}$ × 45 = 270

Reflex angle = 360- (292$\frac{5}{12}$ - 270) = 337$\frac{5}{12}$

Q 9 - At which point of time after 5 O` clock, both hands are at right angle to each other for the first time?

A - 5h, 43$\frac{4}{11}$ min

B - 5h, 43$\frac{6}{11}$ min

C - 5h, 43$\frac{5}{11}$ min

D - 5h, 43$\frac{7}{11}$ min

Answer : B

Explanation

(5n + 15) × $\frac{12}{11}$; here n = 5

$= 40 \times \frac{12}{11} = 43\frac{6}{11}$ min past 5

Answer : C

Explanation

(5n ± 15) × $\frac{12}{11}$; here n = 7

Then, $\frac{600}{11}$ min past 7 and $\frac{240}{11}$ min past 7
