Some question: In a class, 3/5 of the students are girls and rest are boys. If 2/9 of the girls and 1/4 of the boys are absent, what part of the total number of students is present ?
Options:
(A) 17/25
(B) 18/49
(C) 23/30
(D) 23/36
(E) 29/36
Some stream of consciousness:
Girls = 3/5, boys are 2/5
Absentees are (2/9)*(3/5) + (1/4)*(2/5) = 7/30
Present Students are 23/30 The answer: (C).
