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

Answer : D

Explanation

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

Q 3 - A clock strikes 5 taking 8 sec. In order to strike 9 at the same rate the time taken is

A - 14 sec

B - 15 sec

C - 16 sec

D - 17 sec

Answer : C

Explanation

Time taken for first interval = 2 sec

Time taken for 8 intervals = 2 × 8 = 16

Answer : C

Explanation

(5n ± x) × $\frac{12}{11}$ min past n.

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

= 33$\frac{9}{11}$ min past 5 and 19$\frac{12}{11}$ min past 5

Q 5 - If a clock is started at noon then angle turned by hour hand at 4.45 pm is?

A - 142$\frac{2}{4}$

B - 142$\frac{3}{4}$

C - 142$\frac{5}{4}$

D - 142$\frac{6}{4}$

Answer : A

Explanation

(4 + $\frac{45}{60}$) × 30 = 142$\frac{2}{4}$

Q 6 - If a clock strikes at 7 O`clock taking 9 sec in order to strike 10 at the same rate what should be the time taken?
