Sir,
The school will close for the summer vacation next week. We want to go on an educational trip. We want to see the Mountains covered with snow. We also want to visit there famous place.
On our way back, we want to see Shimla. This trip will be very useful to us It will give us first hand knowledge. History as subject will become interesting.
The trip will cost rupees three hundred per head. Our teacher of History has agreed to take us to these places. Thirty boys of my class will go on this trip. I hope you will arrange this trip.
Yours faithfully,

Explanation:
giGiven,
A and B are the two sets which contains 3 and 6 elements respectively
Therefore,
n(A) = 3
n(B) = 6
Maximum no. of elements in AUB
AUB wil be maximum when, the both A and B are Disjoint sets
To find Maximum no. of elements, we have to add the no. of elements of both sets
Therefore,
n(AUB) = n(A) + n(B)
n(AUB) = 3+6
n(AUB) = 9
Minimum no. of elements in AUB
AUB will be minimum, when A is a sub-set of B
If, A C B
Then,
n(AUB) = 6
Hence,
Maximum number of elements in AUB=9
minimum number of elements in AUB=6
