Answer: His room's temperature is 20°C.

Step-by-step explanation:

Since we have given that

Temperature at which water boils = 100°C

According to question, it is 400% more than his room's temperature.

Let his room temperature would be 'x'.

So, our equation becomes,

\dfrac{100+400}{100}\times x=100\\\\\dfrac{500}{100}\times x=100\\\\5x=100\\\\x=\dfrac{100}{5}\\\\x=20^\circ C

Hence, his room's temperature is 20°C.

Answer:

20\°C

Step-by-step explanation:

Let

x------> my room's temperature

we know that

400\%=\frac{400}{100}=4

so

The equation that represent this situation is

4x+x=100

Solve for x

5x=100

x=20\°C
