(b) In an Engineering examination, a student is considered to have failed, secured
second class, first class and distinction, according as he scores less than
45%,between 45% and 60% between 60% and 75% and above 75%respectively.
In a particular year 10% of the students failed in the examination and 5% of the
students get distinction. Find the percentage of students who have got first class
and second class. Assume normal distribution of marks.
