Read the following information carefully and answer the question given below-

The total production by $3$ factories on Sunday was $540$ out of which $\frac{100}{3}\%$ of buses were produced by Tesla. The number of buses produced by Renault on Sunday is less than the buses produced by Tesla on Sunday by the same extent as the number of buses produced by Sonata on Sunday is more than the buses produced by Tesla on Sunday. The difference between buses produced by Renault and Sonata on Sunday is $40$. $150$ buses are produced by Tesla on Monday, which is $100$ less than the buses produced by the same company on Tuesday. A total of $910$ cars were produced by Tesla from Sunday to Thursday. The ratio between buses produced by Tesla on Wednesday to buses produced by the same company on Thursday is $5 : 6$. $220$ buses were produced by Renault on Monday, which is $80$ less than the buses produced by Sonata on Tuesday. A total of $570$ buses were produced on Monday, which is $76\%$ of the total buses produced on Tuesday. The number of buses produced by Sonata on Wednesday is $\frac{200}{3}\%$ more than buses produced by Tesla on the same day. Total $580$ buses were produced on Wednesday. The number of buses produced by Sonata on Thursday is the same as that on Sunday. $140$ buses were produced by Renault on Thursday.

On which pair of days out of the following, the number of buses produced by Tesla is the same?
