@Neelu
Given:
2 candles nd a match box only...
We need to measure 30 mins...
Given:
1 candle burn for 1 hour... remember clock is not given... We need to measure 30 mins with the use of candle nd match box only...
1 candle burn for 1 hr means , 1/2 candle burn for 30 mins...
But there is no measuring instrument given to find the exact half of the candle...

So what we can do is, We can light up both the ends of a candle...
If we light up in one end, it ll burn for 1 hr... If in both ends means , it ll burn for 30 mins...

Suppose if u want to measure 1hr 30 mins, u can light up 1 candle in 1 end... So it ll burn for 1 hr... After that candle gets burned completely (means 1 hr completed), u can light up both the ends of another candle (so it ll burn for 30 mins)

Hope u understand this...
