There are a number of long fuses, of which you only know that they burn for exactly one hour after you light them at one end. However, you don't know whether they burn with constant speed. Fore example, the first half of the fuse is burned in only 10 minutes while the rest takes the other fifty minutes to burn completely. With what least number of fuses can you measure exactly seven eighths of an hour in time? You can safely assume that you have a lighter.

a very old puzzle .

number of candles required is 3.

lit all the three together, but the first one in bth the ends.
so the first one will be burnt out in 1/2 hr. the other two are left over to be burnt for 1/2 hr more.
now lit the second candle in the other end also. so this will burn it in 1/4 hrs. the last one is left to be burnt for 1/4 hrs.
lit @ the other end as well. it will take time of 1/8 hrs.
so total time = 1/2+1/4+1/8 = 7/8

given the question if first half can burn in 10 mins and rest in 50 mins .. we cant assume what u did? can we ?

but there seems no other way to do it

ya exactly,
but the question also says that the candle to be burnt is in 1 hr total.
pls note that we are not considerin the fraction of candle burnt(which wont be uniform obviously ) but the time required -- which will always be 1 hr in total. e.g say after 15 mins the candle will need another 45 mins to burn completely....so here we can take the time as a base.isn't so?

i think this was the trck here in this puzzle...

Keep Rockin...n...Keep Solvin

answers
1 F stands 2nd in race 4 option b)
2 G/E can be 3:1 or 1:3 so cannot be determined exactly option d)
3.its option a) as C , E, G are the rankers their order can be C/E/G or C/G/E but order is immaterial to the question
4. D comes third in race 2 and race 4 so option C
5 .if the points get rearranged either E can come 2nd in 0 race or in 2 races
so option d

3. C,G,E option --> (a).
4. Race #4 ; option -->C.
5. at most 2 races ;option -->d.
