It rained continuously for 10 days
so out of 12 noon , already 10 noons are covered...

A group of workers from the Madadian Kebab Recycling Factory went on a holiday to the sun soaked coast of Madadia. It rained for 13 days. But when it rained in the morning, the afternoon was lovely. And when it rained in the afternoon, the day was preceded by clear morning.

Altogether there were 11 very nice mornings and 12 very nice afternoons. How many days did their holiday last?


Answer:
The holiday lasted for 18 days.

Let's assume the number of days as follows:
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

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

Hence, total number of days on holiday = 18 days



now this ques to be solved in the same way

We went to some place and it rained for 15 days. Clear mornings are followed by rainy afternoons. And all clear afternoons are preceeded by rainy mornings. It rained continuiosly for 10 mornings. It rained for 12 afternoons. And 13 days are without any rain. How many days we stayed in the new place?
Let's assume the number of days as follows:
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

Number of days with rain = X + Y = 15 days ->1eqn
Number of days with clear mornings = Y + Z = 12 days-> 2eqn
Number of days with clear afternoons = X + Z = 10 days ->3eqn
Solve eqn 1& 2 we get x – z = 5 ->4 eqn
Solve eqn 3 & 4 we get x = 13
Substitute x=13 in eqn 1 we get y=2
Substitute y=2 in eqn 2 we get z=10
Hence, total number of days on holiday = x+y+z days.= 13+2+10 =25 days (ans)

Ans: 25
Exp:
It rained for 12 afternoons. And 13 days are without any rain.
So, there r 12+13=25 days stayed in the new place

please can any one give clear explanation for this question
