If 1 student got selected, then 1 rejected
If 2 students got selected, then 1+2 rejected
If 3 students got selected, then 1+2+3 rejected
If 4 students got selected, then 1+2+3+4 rejected
If n students got selected, then (1+2+3+4+...+n) rejected =n(n+1)/2 rejected

For n students to be selected, total students appeared is = students who got accepted + students who got rejected = n+n(n+1)/2

acceptance percentage, n/[n+n(n+1)/2]=5
solving it for n, we got n=37
Therefore accepted students are, n=37
total students are, n+n(n+1)/2 = 37+37(37+1)/2 = 740
