In a class if 1 is absent the rest of them can be divided into 6 equal groups and if two are absent can be divided into 7 equal groups. Find the minimum number of students in the class
Options:
(A) 35
(B) 36
(C) 37
(D) 38
(E) 39 Hmmm, my stream of consciousness:
Multiple of 6 and 7 with difference 1 are 36 and 35
So the number of students in the class is 37 So, the answer is (C).
