Answer / guest
Assume there are 6X boys and 4X Girls
Total Students taking lunch in canteen
= (6X)(60/100) + (4X)(40/100)
= 36(X/10) + 16(X/10)
= 52(X/10)
Total students are = 6X + 4X = 10X
% of class taking lunch in canteen
= ((52X/10) * 100 ) / 10X
= 52 %

Answer / snigdha
Let us assume that the no. of students are 10.
Hence boys are 6 and girls are 4.
60%of 6= 60/100*6=36/10.
40%of 4= 40/100*4=16/10
total students who lunch in canteen = 36/10+16/10=52/10
Total % = (52/10)/10*100
= 52%
