Answer: 24 °C

Explanation:

Mean =
$\frac{\text{Sum of n observations}}{n}$

Given: Mean room temperature from Monday to Saturday = 25°C

Sum of temperature from Monday to Saturday = 6 x 25°C [Total 6 days from Monday to Saturday]

= 150°C

Mean room temperature of Saturday and Sunday = 28°C

Sum of temperature of Saturday and Sunday = 2 x28°C

=56 °C

Sum of temperature from Monday to Sunday = 7 x 26°C

= 182 °C

Room temperature on Saturday = 150°C + 56 °C - 182 °C

= 24 °C

Hence, the room temperature on Saturday = 24 °C
