| LO | 10 |
| FE | 26 |
| TO | 8 |
| PO | 10 |
In Bank E, how many more TOs should be employed than the required number so that the ratio of the number of TOs to the number of FEs becomes 2 to 3?
A42 ✓ Correct
B34
C23
D39
Correct answer: (A) 42
Explanation
The number is 42, so the answer is 42.
In Bank E the FEs are 26 percent of 450, which is 117.
The TOs are 8 percent of 450, which is 36.
For the ratio of TOs to FEs to be 2 to 3, the TOs needed are two-thirds of 117.
That is 78.
So the extra TOs needed are 78 minus 36.
That is 42.
