In an examination, 300 students appeared. Out of these students; 27 % got first division, 54 % got second division and the remaining just passed. Assuming that no student failed; find the number of students who just passed. Choose the correct choice from the following choices
A) 33 B) 57 C) 54 D) 99 E) 01

Rationale: "the number of students with first division = 27 % of 300 = 27 / 100 × 300 = 8100 / 100 = 81 and , the number of students with second division = 54 % of 300 = 54 / 100 × 300 = 16200 / 100 = 162 therefore , the number of students who just passed = 300 – ( 81 + 162 ) = 57 answer : b"
Answer: B
