Question

In a school, students thought of planting trees in and around the school to reduce air pollution. It was decided that the number of trees that each section of each class will plant, will be the same as the class in which they are studying, e.g., a section of class I will plant one tree, a section of class II will plant two trees and so on till class XII. There are three sections of each class. Find(a) How many trees will be planted by the students?

(b) Which mathematical concept is used in above problem?

(c) Which value is depicted in this problem

Answer 1

234 trees will be planted
concept of AP and Quadratic equations is used here 
value depicted in this problem are environental and social

Answer 2

Class 1 will plant 3 trees =1x3 
Class 2 will plant 6 trees =2x3
Class 3 will plant 9 trees  =3x3
class 4 will plant 12 trees =4x3
class 5 will plant 15 trees =5x3
class 6 will plant 18 trees =6x3
class 7 will plant 21 trees = 7x3
class 8 will plant 24 trees =8x3
class 9 will plant 27 trees = 9x3
class 10 will plant 30 trees =10x3
class 11 will plant 33 trees =11x3
class 12 will plant 36 trees =12x3
Then add 36+33+30+27+24+21+18+15+12+9+6+3=234trees.a) The students will plant 234 trees.b) The multiplication concept is used in the above problem.c) 234 is the value depicted in this problem.
