The table shows employees across five cities (total 4260) and the percentage in four departments (HR, Finance, IT, Accounts), which add to 100 per city. Dashes are missing values to be calculated if required.

| Mumbai | 760 | 15 | — | 30 | — |
| Bengaluru | — | 18 | 20 | 32 | — |
| Hyderabad | — | 25 | 18 | — | 35 |
| Gurgaon | 700 | 20 | 20 | — | 22 |
If the number of employees in Bengaluru is 10% less than the number in Hyderabad, then the number of employees working in the Finance and Accounts departments together is more than 415 in exactly how many cities?
Exactly three cities exceed 415, so the answer is three.
Delhi, Mumbai and Gurgaon together have 2360 employees, leaving 1900 for Bengaluru and Hyderabad.
With Bengaluru 10% less than Hyderabad, Hyderabad has 1000 and Bengaluru has 900.
Finance plus Accounts is 46% for Delhi giving 414, and 55% for Mumbai giving 418.
It is 52% for Bengaluru giving 468, 42% for Gurgaon giving 294, and 60% for Hyderabad giving 600.
So the totals above 415 occur in Mumbai, Bengaluru and Hyderabad.
That makes exactly three cities.
