The equations for the lengths of the candles (in terms of time) let H be the initial ht of 2 candles.let thicker candle be 2x & other be x after some time. let the length of both the candles be 'x'. Correct answer is 3 hours. 360:240 2 hours Source: CoolInterview.com Answered by: Tushar  Date: 10/16/2009  Contact TusharSuppose the length of both candles is 12 cm(l.c.m of 4&6).After lighting, the thick candle is getting reduced by 2cm/hr while the thin candle is getting reduced by 3 cm/hr. after 3 hrs the thick candle will be of 6 cm while the thin candle will be of 3 cm.
