Solution :-
Total number of seats → 820
Sale of total tickets → 648
Number of sold tickets guessed by first usher
→ 3/4 of 820 = 3/4 × 820 = 615
Number of sold tickets guessed by the second usher
→ 2/3 of 820 = 2/3 × 820
1640 = 546.66 ≈ 547
Since, 615 is more close to 648 than 547
Therefore, first usher made the better guess
