A reversible engine converts one-sixth of the heat input into work. When the temperature of the sink is reduced by \(62 K\), the efficiency of the engine is doubled. The temperatures of the source and sink are
- \(80^{\circ} \mathrm{C}, 37^{\circ} \mathrm{C}\)
- \(95^{\circ} \mathrm{C}, 28^{\circ} \mathrm{C}\)
- \(90^{\circ} \mathrm{C}, 37^{\circ} \mathrm{C}\)
- \(99^{\circ} \mathrm{C}, 37^{\circ} \mathrm{C}\)
Answer
(D) 99^ C , 37^ C
