A can complete a piece of work in 24 days and B can complete it in 28 days. If they work on alternate days, starting with B on the first day, then in how many days will the work be finished?
25 \( \frac{6}{7} \)
25 \( \frac{1}{6} \)
24 \( \frac{6}{7} \)
24 \( \frac{1}{6} \)
A group of numbers and symbols is coded using letter codes as per the codes given below and the conditions that follow. Study the given codes and conditions and answer the question that follows.
Note: If none of the conditions apply, then codes for the respective number/symbol are to be followed directly as given in the table.
| Number/Symbol | * | 2 | 5 | 7 | $ | + | 8 | % | # | 9 | & | 6 | $ | 4 |
| Code | H | D | O | A | B | P | B | Q | Z | Y | R | B | U | F |
Conditions:
If the first element is a symbol and the last an odd number, the codes for these two (the first and the last elements) are to be interchanged. If the first element is an odd number and the last an even number, the first and last elements are to be coded as ©.
If both second and third elements are perfect cubes, the third element is to be coded as the code for the second element.
What will be the code for the following group?
# 8 9 $
