Explanation:

Let’s break this down step by step:

- Each team plays every other team twice (home and away), so each team plays 6 matches.

- Scoring system: +2 points per goal scored, -1 point per goal conceded, +5 points per match win.

- Chennai won 3 matches; Mumbai won 5; Delhi and Kolkata split the rest (each won 2).

- Two matches between Delhi and Kolkata ended in draws: same number of goals.

- In one specific Chennai vs. Delhi match:

  - Chennai scored 2 more goals than Delhi.

  - Chennai’s game point = 7, Delhi’s game point = 1.

Here’s what really matters for the last bit:

- Let’s say Delhi scored x, Chennai scored x+2.

- For Chennai: (x+2)*2 - x*1 = 7 ? 2x + 4 - x = 7 ? x = 3 (so Chennai scored 5, Delhi 3)

- For Delhi: x*2 - (x+2)*1 = 1 ? 2x - x - 2 = 1 ? x - 2 = 1 ? x = 3 (matches above)

So:

- Chennai: 5 goals, Delhi: 3 goals.

- Average goal per team: (5+3)/2 = 4

Correct Option:

Option:4, 4

The rest:

- Option 1, 2, 3, 5 – these don’t fit the numbers above.

- All statements are consistent with the calculations.

- Draw matches info just confirms both teams are equal for those games, doesn’t affect this calculation.

If you get 4, you get the math and the rules. Nice work.
