Before looking at the question, please read the instruction carefully.
INSTRUCTION: The below given question is just for self analysis of how much time you take to solve it. If you can solve the question WITHIN 43 SECONDS after reading the QUESTION, then, you are exceptional (according to me).
QUESTION: 2 Candles, one of which is 3 cm longer than the other, are lighted. The longer one is lighted at 5:30 p.m. and shorter one at 7.00 p.m. At 9.30 p.m. , they are at the same level. The longer burns out at 11.30 p.m. and shorter at 11.00 p.m. If the original lengths of the 2 candles are A and B (in cm). Find (A+B).
