It was a bright sunny morning when Akash stood in his school’s assembly ground, thinking about the adventures he would have in Mukteshwar. Yes, they were going to the much awaited Adventure Camp!
They would live in tents, trek in the forest, spot some flora and fauna, climb the rocks, observe the valleys, perhaps make their own food and what not. Akash just could not stop gushing.
“Hurry up boys, fall in line” said the Principal. The Principal, Dr. Sharma was a man of beliefs and ideals. Taking students out for camps and observing them in the vicinity of nature was his mode of working and re - enforcing appreciation for natural environment among them.
Within no time the teachers and all the students gathered in the ground. Dr. Sharma continued, “You are representing your school in this Adventure Camp. So, behave, act and perform well. Be disciplined and do not harm the nature. I hope you would not let us down. Well, you would go to Mukteshwar by bus. Now, stand in order and move towards your buses.”
The students stood in lines – class and section wise. There were exactly 10 students per section. The students lined up as follows.

10 teachers, including Dr. Sharma, were to accompany the students. All moved outside to board the buses.
Mrs. Saxena, the coordinating teacher exclaimed, “We have got only 4 mini buses; how do I adjust the students?”
Mr. Singh, the sports teacher, came forward and said, “Ma’am, I can see we have 4 buses in which 3 buses are 15 seater and 1 bus is 25 seater. That makes it
15×3 + 25×1
= 45 + 25
= 70 seats.
So, that should be enough.”
Mrs. Saxena explained, “But Mr. Singh, we need to adjust the students with least disturbance. The criteria is that each bus should have atleast
two teachers; and
two students of the same section.”
