A solution is to be kept between 30°C and 35°C. What is the range of temperature in degree Fahrenheit?

उत्तर

Let x degree Fahrenheit be the temperature of the solution. 

Then, `30° C< x° F < 35° C` 

Now,` f = 9/5 C +32` 

⇒`9/5xx30+32< x° F < 9/5xx35+32` 

⇒` 54+32<x63+32`

⇒ `86° < x° < 95°`

Hence, the range of the temperature in Fahrenheit is between  86° and 95°.
