Question

The temperature in Siachen was recorded by mistake as $-21°C$ which was $-25°C$. What is the difference between both the temperatures $?$

Answer 1

Given that the actual temperature of Siachen was $-25°C$ and

the temperature recorded by mistake as $-21°C$

Now, the difference in the temperature of Siachen $=$Actual temperature $~$Temperature recorded by mistake

$=(-25°c)-(-21°c)$

$$\begin{gathered} =-25°c+21°c \\ =-4°c \end{gathered}$$

Hence, the difference of actual temperature and temperature recorded by mistake in Siachen is $-4°c.$
