Last Updated : 26 Mar, 2026
Given two candles, each of which takes one hour to burn completely. They burn unevenly in different parts, though. You also have a box of matches. Using only these candles and matches, measure 45 minutes and 15 minutes.

Check if you were right - full answer with solution below.
**Solution:
**Step 1: At 0 Minutes:
Starting at the same time,
- Light Candle 1 from both ends.
- Light Candle 2 from one end only.
**Step 2: At 30 Minutes:
- Candle 1 burns out completely, as both its ends were burning.
- Candle 2 has been burning from one end for 30 minutes, so it has exactly 30 minutes' worth of wax left. Now light it from the other end.
**Step 3: At 45 Minutes:
- Candle 2 had a remaining 30-minute worth of wax, so it burns in 15 minutes.
So, Candle 1 burning out measures 30 minutes, Candle 2 burning out measures the next 15 minutes, and together they total 45 minutes.
