Answer 2

The students was on his vacation for a total of 9 days.

Given,

rained 7 times in morning or afternoon

there were 5 clear afternoons

there were 6 clear mornings

as only once per day it rained, we have,

$d= \dfrac{(5+6)+7}{2}$

$d=\dfrac{18}{2}=9$

Therefore, d = 9 days.

Hence the students was on his vacation for a total of 9 days.
