Answer 1

Correct Answer - Option 1 : 800 

Given

Average number of car sold on Monday, Tuesday and Wednesday = 500

Formula used

Average = Sum of all observations/ Number of observations

Calculation

Total number of cars sold on Monday, Tuesday and Wednesday = 3 × 500

⇒ 1500

Cars sold on Wednesday = 1500 - 700

⇒ 800

∴ 800 cars sold on Wednesday.
