$$\begin{array}{ccccc}{15}^{th}May& {16}^{th}May& {17}^{th}May& {18}^{th}May& {19}^{th}May\\ 60\%& 40\%& 62\%& 98\%& 74\%\end{array}$$

• A. 18^th May
• B. 19^th May
• C. 17^th May
• D. 16^th May

Answer 1

The correct option is A

18^th May

Rain occurs when the air is unable to hold any more water as water vapour. This means that the air is already holding the maximum amount of water it possibly can and that there is more water present which appears as rain. Thus, rain usually occurs when high value of humidity is present. On 18^th May the humidity is very high (98%), Thus the city experienced rainy weather on that day.
