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 | 3 | 9 | @ | & | 2 | 7 | 5 | % | 1 | 8 | Δ | 4 | 6 |
| Code | L | C | Z | M | D | W | A | P | R | T | F | B | K |
Conditions:
(i) If the first element is a symbol and the last a number, the codes for these two (the first and the last elements) are to be interchanged.
(ii) If the first element is an odd number and the last an even number, the first and last elements are to be coded as ©.
(iii) If both second and third elements are perfect squares, the third element is to be coded as the code for the second element.

Two pipes, A and B, can fill a tank of 7800 litres in 12 hours and 10 hours, respectively. If they are opened together, how many hours will they take to fill an empty tank of 8800 litres?
\( \frac{70}{13} \) hours
\( \frac{89}{13} \) hours
\( \frac{88}{13} \) hours
\( \frac{80}{13} \) hours
If the ratio of two numbers is 17 : 6 and the product of their LCM and their HCF is 102, then the sum of the reciprocals of the LCM and the HCF is:
\( \frac{103}{109} \)
\( \frac{103}{105} \)
\( \frac{103}{102} \)
\( \frac{103}{132} \)
