Answer the next 3 questions based on the information given below.
The currency of the country Papaya is Laugh (Lh). There are exactly five denominations in which the currency is available – Lh 2, Lh 4, Lh 5, Lh 7 and Lh 11.
Each of five persons, A through E, had notes of exactly one denomination with him and no two persons among the five had notes of the same denomination. On a particular day, the five persons visited a shop and each of them purchased a different product. The amounts that A through E paid the shopkeeper were Lh 280, Lh 278, Lh 336, Lh 300 and Lh 660, in that order. Further, the number of notes that each person gave the shopkeeper was distinct. However, the amount that each person paid the shopkeeper was more than the price of the product that he purchased. Therefore, the shopkeeper returned the excess amounts to each of A through E in the form of 3 notes, 1 note, 2 notes, 4 notes and 2 notes respectively, but in denomination(s) different from that in which the person had paid the shopkeeper.
What is the total number of notes that the five persons paid the shopkeeper?

Answer the next 4 questions based on the information given below.
Four employees P, Q, R and S are evaluated on four different parameters – Coding, Technical Skills, Networking and Temperament. Each employee was given a score, which was an integer between 1 and 7 (both inclusive) on every parameter. No employee scored equal on any two of the four parameters. Similarly, no two employees scored equal on any of the four parameters.
Further it is known that:
- The average scores of the four employees in the parameters Coding, Technical Skills, Networking and Temperament were 3, 5, 4 and 5 respectively.
- The sequence of the employees, when arranged in descending order of the scores received in Coding was R, P, S and Q.
- The sequence of the employees, when arranged in descending order of the scores received in Technical Skills was Q, S, R and P.
- The sequence of the employees, when arranged in descending order of the scores received in Networking was P, Q, R and S.
- The sequence of the employees, when arranged in descending order of the scores received in Temperament was S, Q, P and R.
- P did not get 6 in any of the parameters while R got 6 in exactly one parameter.
Which of the following employees did not score 7 out of 7 in any of the given parameters?
- (a)
Only R
- (b)
Only S
- (c)
Both S and R
- (d)
Neither S nor R
