From the given details we get to know that the temperature in Srinagar is as follows
The temperature on Monday = −5°C
Temperature on Tuesday = Temperature on Monday −2°C = −5°C − 2°C = −7°C
Temperature on Wednesday = Temperature on Tuesday + 4°C = −7°C + 4°C = −3°C
Accordingly, the temperature on Tuesday and Wednesday was −7ºC and −3ºC respectively.
