Given:

At Srinagar temperature was $-5^{\circ}\ C$ on Monday and then it dropped by $2^{\circ}\ C$ on Tuesday. 

On Wednesday, it rose by $4^{\circ}\ C$.

To do: 

We have to find the temperatures of Srinagar on Tuesday and Wednesday.

Solution:

The temperature on Monday $=-5^{\circ}\ C$

The temperature dropped by $2^{\circ}\ C$ on Tuesday. 

This implies,

The temperature on Tuesday $=-5 - 2$

$=-7^{\circ}\ C$

The temperature of Srinagar on Tuesday was $-7^{\circ}\ C$.

On Wednesday, it rose by $4^{\circ}\ C$.

This implies,

The temperature on Wednesday $=-7 + 4$

$= -3^{\circ}\ C$

Hence, the temperature of Srinagar on Wednesday was $- 3^{\circ}\ C$.
