Question

3. The number of candidates who appeared in a examination was 13000.
Of which 45% were boys and remaining girls. If 30% of the boys and
40% of girls qualified the examination, find number of candidates who
did not qualify.​​

Answer 1

Answer:

Percentage of students who won prizes = 10+12%=22%.

22%of 30,000 won prizes, i.e. 22/100×30,000= 6,600 students.

-> 22% students won prizes which in number are 6,600 students out of 30,000.
