Question

A family went for a vacation. Unfortunately, it rained daily for $13$ days when they were there. But whenever it rained in the mornings, they had clear afternoons and vice versa. In all, they enjoyed $11$ mornings and $12$ afternoons. How many days in all did they stay there?

• A. $18$
• B. $15$
• C. $20$
• D. $23$

Answer 1

The correct option is A $18$

We will consider morning and afternoon as half day.
$11$ mornings $+$ $12$ afternoons $=23$ half days.
$23-13$ days of raining $=10$ half days
i.e., $5$ mornings and $5$ afternoons are there with no rain.
Therefore, they stayed for $13+5=18$ days.
