In 2016, out of the total students, who did not pass the exam, 20% re apply for the exam in 2017. (In 2017 total students enrolled = reapplied from 2016 + new applicants). The ratio between students passed in 2013 and 2017 is 3: 2. Out of the total passed students in 2017, 96% are new applicants, then find the number of re-applied students from 2016 who did not pass in 2017.

Explanation

Re applied students from 2016 = (450 − 150) × 20 100 = 60 Students passed in 2017 = 75 × 2 3 = 50 New applicants in 2017, out of passed students = 50 × 96 100 = 48 Number of re applied students who passed in exam in 2017 = 50 − 48 = 2 So, no. of re applied students who didn’t pass in exam in 2017 = 60 − 2 = 58 40 Adda247 | No. 1 APP for Banking & SSC Preparation Website: bankersadda.com | sscadda.com | adda247.com | Email: blogger@adda247.com
