kinetic energy of gas is given by K.E=\frac{3}{2}nRT

therefore, kinetic energy is directly proportional to temperature.
so, if we find out percentage change in temperature , we can get percentage change in kinetic energy .

percentage change in temperature = \frac{\Delta{T}}{T_i}\times100

= (390 - 300)/90 × 100
= 90/300 × 100
= 30 %

hence, percentage change in kinetic energy of neon gas is 30%
