Let the total no. of boys = x
then, the boys gone to ground =x/2
also the boys went to lib. = x/4
boys went to other work= 10 
acc. to ques. 
x/2 + x/4 + 10 = x 
by taking lcm, 
(2x +x +40) /4 = x
3x + 40 = 4x
40= 4x - 3x
40= x
 checking,,
put x = 40
40/2 + 40/4 + 10 = 40
20 +10 +10 = 40 
40 = 40
l.h.s. = r.h.s.
checked so total no. boys is 40.....
