A Carnot engine operating between temperatures \( T_{1} \) and \( T_{2} \) has efficiency \( 1 / 6 \). When \( T_{2} \) is lowered by 62
\( \mathrm{P} \) \( K \), its efficiency increases to \( 1 / 3 \). Then \( T_{1} \) and \( T_{2} \) are,

W respectively
(1) \( 372 \mathrm{~K} \) and \( 310 \mathrm{~K} \)
(2) \( 372 \mathrm{~K} \) and \( 330 \mathrm{~K} \)
(3) \( 330 \mathrm{~K} \) and \( 268 \mathrm{~K} \)
(4) \( 310 \mathrm{~K} \) and \( 248 \mathrm{~K} \)
