1. Only II
2. Only I
3. Neither I nor II
4. Both I and II

Answer 1

Correct Answer - Option 4 : Both I and II

Formula used:

Average of n numbers = Sum of all numbers/n

Calculation:

Checking I:

Ratio of number of cars manufactured by company C4 to the number of cars manufactured by company C6 = 1800 : 2800 = 9 : 14

⇒ Statement I is true

Checking II:

Total cars manufactured = 2600 + 3200 + 4200 + 1800 + 2200 + 2800 + 3500 = 17300

Average of cars manufactured per company = 20300/7 = 2900

⇒ Statement II is true

∴ Both statements I and II are true
