A clock takes 7 seconds to ring bell at 7 o'clock. How long will it take for the same clock to ring bell at 10 o'clock?
Read Solution (Total 9)

- 10.5 seconds; in sense that timer starts at first ring and the first ring is at time t=0 seconds and 7th ring is at time t=7 seconds. So, in 7 seconds, only 2nd, 3rd, 4th, 5th, 6th, and 7th are to be considered. So, 6 rings in 7 seconds means 3 rings in 3.5 seconds. so, at 10, only 9 rings add to the timer, each 3 of which takes 3.5 seconds. so total = 3*3.5 = 10.5 seconds. i think i have read it somewhere, uhh... in some puzzle book.

- in between ringing 7 times gap are 6
so in 10 times are 9
6 gaps .....7 sec
9 gaps...... (7/6)*9 =10.5 sec - 9 years agoHelpfull: Yes(1) No(0)
- it takes 10 sec because it ring 10 times on 10 O'clock

- bong--bong--bong--bong--bong--bong--bong in this -- represent time -- are 6 so 7/6= for one gap 1.16
hence for 10 time it gives nine gap 1.16*9= 10.5
10.5 write time - 6 years agoHelpfull: Yes(0) No(0)

1000 men are standing in a circle, numbered 1, 2, ..., 1000. 1 takes a sword, kills 2 and hands over sword to 3, who takes it, kills 4 and gives it to 5. This reapeats in the circle. That is, whoever gets the sword kills the one near him and hands over the sword to the next. If this continues, what is the number of the man that survives?
