Answer Posted / pappu kumar yadav
Let the length of both the candles be"l".By the qstn in 6
hrs thicker candle consumes "l" length.Hence in "t" time it
consumes"(l/6)t".(where "t" s d duration during whch bth d
candles glow n chkd).Similarly during"t" time thinner
candle consumes"(l/4)t".This implies that after "t" time
length of thicker candle remaining =l-(lt/6).Length of
thinner candle remaining=l-(lt/4).Now by the question we
have (1/2)*[l-(lt/6)]=l-(lt/4). on solving this we get t=3
Hours. Hence bth d candles were lit 3 hours before.
