Answer Posted / mathsskumar_sarma2000
let x be lenghth of candles.
thicker one---- in 1 hr 1/6th will go.
thinner one--- in 1 hr 1/4th will go.
let he lit for n hrs.
so in n hrs thicker one goes n/6.
and thinner one goes n/4.
so remainini length are x-n/6 and x-n/4.so x-n/6=2(x-n/4)
implie n=3x. if x=1 n=3hrs.
