Answer:
The holiday lasted for 18 days.
Explanation:
Let's assume the number of days are as following:
let the rain in the morning and lovely afternoon = X days
Clear morning and rain in the afternoon = Y days
No rain in the morning and in the afternoon = Z days
Now according to the question
Number of days with rain = X + Y = 13 days
Number of days with clear mornings = Y + Z = 11 days
Number of days with clear afternoons = X + Z = 12 days
Solving above 3 equations, we get
X = 7, Y = 6 and Z = 5
Now total number of days on holiday = X+Y+Z = 7+6+5 =18
Hence, total number of days on holiday = 18 days.
