<PRE><B>Question 1044116</B>
If 4 students sit on each bench, 
Number of benches sat on= x/4 
Total number of benches available= (x/4)+3 
If 3 students sit on each bench, 
Number of benches needed= x/3 
3 students are left standing 
Thus, 1 bench is needed 
Therefore, number of benches available= (x/3) -1 
Thus, 
(x/4)+3 = (x/3)-1 
x/4 + 3= x/3 – 1 
x/4 – x/3 = -1-3 
3x/12 – 4x/12 = -4 (L.C.M) 
-x/12 = -4 
-x = -4*12 
-x = -48 
so, x=48 

Number of students in the class = x = 48
