Supposing a clock takes 7 seconds to strike 7. How mlong will it take to strike 10?

• Hey friends,Please ignore my previous solution.
  Its correct ans. will be:
  
  7 strike of a clock have 6 intervals
  while 10 strikes have 9 intervals.
  
  Required time =(7/6 *9) seconds =10 1/2 seconds.
  
  Because time is only moving ahead ! so when we say between 1 to 2 hours, that means we assume only 1 hours not 2 hours.

• ANS.-10807
  1 hour=60 min i.e. 3600 sec
  7 hrs+3 hrs=10 'o'clock
  so, 3 hrs=3600*3=10800 sec
  so it'll take 10807 sec to strike 10.

• 1 hour=60 min i.e. 3600 sec
  7 hrs+3 hrs=10 'o'clock
  so, 3 hrs=3600*3=10800 sec
  so it'll take 10807 sec to strike 10.

• I think the question is asked about a clock hand, no matter which one it is to strike 10, As it is given the the hand is on 7 then 15 seconds more to 10 i.e 15/60 mnts= .25 mnts

• 0.5 seconds.
  
  The timer will start only at the first strike. So, the first strike really doesn't count. So, in striking 7, the 7-second interval is for the last 6 strikes. Since the strikes are spaced uniformly, it means each 3 strikes take 3.5 seconds.
  
  To strike 10, it needs 1 + 3 + 3 + 3 = 10 strikes, which will require 0 + 3.5 + 3.5 + 3.5 = 10.5 seconds.
