JEE Advanced 2023 Physics question on Thermodynamics

One mole of an ideal gas expands adiabatically from an initial state (TA,V0)(T_{\text{A}}, V_0) to final state (Tf,5V0)(T_{\text{f}}, 5V_0). Another mole of the same gas expands isothermally from a different initial state (TB,V0)(T_{\text{B}}, V_0) to the same final state (Tf,5V0)(T_{\text{f}}, 5V_0). The ratio of the specific heats at constant pressure and constant volume of this ideal gas is γ\gamma. What is the ratio TA/TBT_{\text{A}}/T_{\text{B}}?
  1. A.
    5γ−15^{\gamma-1}
