Answer: 312
Step-by-step explanation: According to the question , there are two sections of each class so the number of trees that are planted by students of class I, class II, class III, …..& class XII are:
Number of trees planted by the students of two sections of class I=2×2=4
Number of trees planted by the students of two sections of class II=2×4=8
Similarly,
Number of trees planted by the students of two sections of class 3=2×6=12
Number of trees planted by the students of two sections of class12=2×24=48
So, the number of trees planted by the students of two sections of different classes are4,8,12,……48
This series forms an AP
Here,first term(a)=4, common Difference (d)=8–4=4, last term (l)=48 and (number of terms)n=12
Number of trees planted by the students =sum of 12 terms of above AP
