A Carnot engine operating between temperatures $T_{1}$ and $T_{2}$ has efficiency $\frac{1}{6}$. When $T_{2}$ is lowered by 62 K, its efficiency increases to $\frac{1}{3}$. Then $T_{1}$ and $T_{2}$ are, respectively:\\
(1) 372 K and 330 K\\
(2) 330 K and 268 K\\
(3) 310 K and 248 K\\
(4) 372 K and 310 K
