A Carnot's engine is working between a source at constant temperature T_1 and a sink at constant temperature T_2 has efficiency is \frac{1}{8}. Upon decreasing the temperature of sink by 50^{\circ} {C}, the efficiency becomes \frac{1}{4}. Then the values of T_1 and T_2 are

Correct Answer is : T1=127∘C,T2=77∘C

{T}_1=127^{\circ} {C}, {T}_2=77^{\circ} {C}

{T}_1=400^{\circ} {C}, {T}_2=315^{\circ} {C}

{T}_1=215^{\circ} {C}, {T}_2=100^{\circ} {C}

{T}_1=100^{\circ} {C}, {T}_2=215^{\circ} {C}
