Let average of all persons = x
∴ (13 × 79) + 6(x + 4) = 19 × x
13 × 79 + 6x + 24 = 19x
13 × 79 + 24 = 13x

Total money spent = 1536

Question Analysis:
- There are 19 persons who went to a hotel for a dinner party.
- Out of the 19 persons, 13 of them spent `79 each on their dinner.
- The remaining persons spent `4 more than the average expenditure of all the 19 persons.
- We need to find the total money spent by all the persons.

Solution:
Let's solve this problem step by step:

Step 1: Calculate the total expenditure of the 13 persons who spent `79 each on their dinner.
Total expenditure of 13 persons = 13 * `79 = `1027

Step 2: Find the average expenditure of all 19 persons.
Average expenditure of all 19 persons = Total expenditure / Number of persons
Average expenditure = `1027 / 19 = `54.05 (approx)

Step 3: Calculate the total expenditure of the remaining 6 persons who spent `4 more than the average expenditure.
Total expenditure of 6 persons = 6 * (`54.05 + `4) = 6 * `58.05 = `348.3 (approx)

Step 4: Find the total money spent by all the persons.
Total money spent = Total expenditure of 13 persons + Total expenditure of 6 persons
Total money spent = `1027 + `348.3 = `1375.3 (approx)

Therefore, the correct answer is option 'D' - None of these.
