Answer :

Given:

Seats in picture hall = 820

Persons reported in hall = 648

Guess made by 1^{st} user = full

Guess made by 2^{nd} user = full

Formula Used\Theory:

Less the difference between guessed value and real value

More it will be a better guess.

⇒ The guess made by 1^{st} user:-

full = × 820

= 3 × 205

= 615

Difference in reality and guessed = 648 – 615

= 33

⇒ The guess made by 2^{nd} user:-

full = × 820

= 2 × 273.33

= 546.66

Difference in reality and guessed = 648 – 546.66

= 101.33

∴ The difference of guessed from reality is lower in 1^{st} user

Conclusion:1^{st} user made a better guessed
