The number of trees planted by the students is 312

Step-by-step explanation:

Step 1 :

Given,

Number of trees which each class plants = 2 * the class in which they study

There are 2 classes in each section.

Step 2 :

Number of trees which 1 section of class 1 planted  = 1 * 2

Number of trees which 2 sections of class 1 planted  = 1 * 2 * 2

Number of trees which 1 section of class 2 planted  = 2 * 2

Number of trees which 2 sections of class 2 planted  = 2 * 2 * 2

Following the pattern we have ,

Number of trees which 1 section of class n planted  = n * 2

Number of trees which 2 sections of class n planted  = n * 2 * 2

Step 3 :

There are 1 to 12 classes

So

The total number of trees planted is (1+2+3+4+5+6+7+8+9+10+11+12) *2 *2 = 78* 4 = 310

Step 4 :

Answer:

The number of trees planted by the students is 312
