Seven persons- P, Q, R, S, T, U and V work in banks at different designations but not necessarily in the same order. The designations are in decreasing order viz., Chief Executive officer(CEO), Territorial Head(TH), Branch Manager(BM), Financial Analyst(FA), Bank Accountant(BA), Front Desk Employee(FDE) and Clerk such that CEO is the seniormost designation whereas Clerk is the junior most designation.
| Designation | Person | No. of countries |
| Chief Executive officer(CEO) | | |
| Territorial Head(TH) | | |
| Branch Manager(BM) | | |
| Financial Analyst(FA) | | |
| Bank Accountant(BA) | | |
| Front Desk Employee(FDE) | | |
| Clerk | | |
Only two persons are senior to S, who visited 5 countries.

U is immediate junior to R and also junior to S.
The difference between the number of countries of U and S is 4.
The number of persons junior to U is same as the number of persons senior to V, who visited a prime number of countries.
Prime number countries = 3, 7
