Question

The ratio of number of students in three different classes A, B and C of a school is 3:5:4. Find the maximum possible number of students in class C, if the strength of the school is not more than 400. (Assume there are only A, B and C classes in the school) A.168 B.152 C.132 D.148 E.cannot be found

Answer 1

let the students in each class be 3x 5x and 4x
total students in class = 400
3x +5x + 4x = 400
12x = 400
x = 400 /12
   = 33
students in class 132 
correct option = c
