if a man lights a cndle n extinguishes it when its one third burnt then in how many days will

let the candle is 10m long then 10% of it will be 1m and when we calculate 1/3 of each day then:
1st day = 10-(10/3)=20/3m
2nd day = 20/3 - (20/9) = 40/9m
.
.
.
so on the 6th day the candle would be of it's 10% means 1m...

the answer is six
on solving you will get GP like this
1/3 + 2/9 + 4/27 ...
compare it with 90% i.e. 9/10 and you will get the answer

Everyday 2/3 of it will remain.It will follow g.p.
write the remaining amount for everyday after he extinguishes it and compare it with 1/10.
day 1=2/3
day 2=4/9
day 3=8/27
day 4=16/81
day 5=32/243>1/10
day 6=64/729

let the total be 100% then on the 1st day 100*1/3=33.33 % will be remainning and on the 2nd day 33.33*1/3=11.11 then on the 3rd day it will be less than 10% so i think the anser is 3

Each day it will remail 2/3. solve (2/3)^6 approx. it will be (1/10)
