|As Per The Given Circuit Load Impedance Is 25 Ohms Than Reflection Coefficient Is Modified To (25-100)/(25+100) = (-75)/125 = -0.6.|

|Look at the question carefully, they mentioned reflection from source end.|

|The reflection coefficient (γ) measures the amplitude of the reflected wave versus the amplitude of the incident wave. The expression for calculating the reflection coefficient is as follows:
γ = (ZL - ZS)/(ZL + ZS).
Where ZL is the load impedance and ZS is the source impedance.
Therefore, (100-200)/(100+200) = -0.33333 i.e. 1/3.

|I agree @Malathi, he asked source end so answer 1/3.|
