In a class of 50 students, 3/5 went away do painting, 1/5 went to play in the field. How many students are left in the classroom? Options
A) 20	B) 30	C) 5	D) 8	E) 10
3/5 + 1/5 are the students who have left the classroom   3/5 + 1/5 = (3 + 1)/5 , since denominator is same for both fractions   = 4/5   Remaining students in the classroom = 1 - 4/5 = 5/5 - 4/5 = (5-4)/5 = 1/5   1/5 of 50 = 10   Ans: 10
