Question

The temperature recorded of a certain city was observed to be ${18}^{\circ }\text{C}$ in the morning. When the temperature was observed in the evening, it was dropped by $7^{\circ }\text{C}$. What is the recorded temperature in the evening?

• A. ${25}^{\circ }\text{C}$
• B. ${18}^{\circ }\text{C}$
• C. ${10}^{\circ }\text{C}$
• D. ${11}^{\circ }\text{C}$

Answer 1

The correct option is D ${11}^{\circ }\text{C}$

Temperature observed in the morning $={18}^{\circ }\text{C}$

In the evening, the temperature was dropped by $7^{\circ }\text{C}$.

$\therefore$ To get the actual temperature in the evening, we need to subtract $7^{\circ }\text{C}$ from the temperature that observed in the morning.

Hence, the actual temperature recorded in the evening $={18}^{\circ }\text{C}-7^{\circ }\text{C}$
$=\underset{–}{{11}^{\circ }\text{C}}$

Therefore, option (d.) is the correct one.
