Answer:
[tex]20\°C[/tex]
Step-by-step explanation:
Let
x------> my room's temperature
we know that
[tex]400\%=\frac{400}{100}=4[/tex]
so
The equation that represent this situation is
[tex]4x+x=100[/tex]
Solve for x
[tex]5x=100[/tex]
[tex]x=20\°C[/tex]
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,
[tex]\dfrac{100+400}{100}\times x=100\\\\\dfrac{500}{100}\times x=100\\\\5x=100\\\\x=\dfrac{100}{5}\\\\x=20^\circ C[/tex]
Hence, his room's temperature is 20°C.
