Question
If in year 2014, 20% of students who applied for Post
Graduation also applied for Graduation then the numbers of students who apply only for Graduation are what percent of number of students who apply only for Post Graduation in year 2014. The line graph shows the number of students (in Lakh) who applied for Graduation and Post Graduation over different years.Solution
Students only apply for Graduation in 2014 = 25 – [20/100 × 20] = 21 Lakh Required% = [21/(20 – 4)] × 100 = (21 × 25)/4 = (525/4)%
