Question

5. When a clock strikes 10 in 27 seconds, it will strike 5 in how many seconds
(a) 12
(b) 15
(c) 22
(d) 20
​

Answer 1

Step-by-step explanation:

Between 1 o'clock to 6 o'clock there are 5 gaps of time

Now 5 intervals of time takes 10 seconds so 1 interval of time takes 2 seconds i.e. we hear the strike in a clock after every 2 seconds Now 12 strikes will have 11 intervals which takes 11 X 2 i.e. 22 seconds

Answer 2

Answer:

For 5 strikes,it takes 12 seconds

Step-by-step explanation:

Given that,

A clock strikes 10 in 27 seconds

We know that,for 10 strikes,there are 9 intervals of time

Time for 9 intervals=27seconds

==>Time for each interval=3seconds

Now,For 5 strikes,4 intervals of time are required.

Hence,time for 5 strikes = 4 x 3 sec =12 seconds

Therefore,required time is 12 seconds
