It is very simple, since the data given is ungrouped. All you have to do is multiply the marks obtained and the no of students who obtained it. Then add all the marks and divide it with the total no of students. So the answer is

10*6+11*3+12*4+13*5+14*7+15*5 divide by 6+3+4+5+7+5

which is equal to 

60+33+48+65+98+75/30

so the answer is 379/30 or 12.6
