Correct Answer - Option 4 : 3°C

Given:

Temperature on Monday = (-5)°C

Decrement in temperature = (-2)°C

Increment in temperature = (4)°C

Calculation:

Temperature on Monday = (-5)°C

Decrement in temperature = (-2)°C

⇒ Total decrement in 3 days = (-2) °C × 3 = (-6)°C

Increment in temperature = (4)°C

⇒ Total increment in 2 days = 4C × 2 = 8°C

⇒ Temperature after 5 days from Monday = (-5) °C + (-6)°C + 8°C = (-3)°C

Temperature after 5 days from Monday = (-3)°C

Additive inverse of the number = 3°C

∴ The additive inverse of the temperature after 5 days from Monday is 3°C.

 

The additive inverse of a number 'x' is the number that, when added to 'x', yields zero. This number is also known as the opposite (number), sign change, and negation.

e.g. - Additive inverse of -3 will be -3 + 3 = 0 i.e. 3
