19) F

__1: Correct__

3 gold + 5 silver = (3 x 3) + (5 x 2) = 19

Population of Norway = 4.6 million

Medals per million = 4.5

19 ÷ 4.6 = 4.5 per million

__2: Wrong__

Population of Iceland = 0.3 million

Even if all 3 medals were bronze, weight = 3

Number of medals per million = 3 ÷ 0.3 = 10

The figure given is 6.8 which is wrong

__3: Correct__

Population of Slovenia = 2 million

Number of medals per million = 4.5

Total weight of medals won = 4.5 x 2 = 9

Medals won by Slovenia = 6

1 gold medal = 3

Weightage of the other 5 medals = 9 -3 = 6

This could be 1 silver, and 4 bronze

(2 x 1) + 4 = 6

So this scenario could be correct.

Statements 1 and 3 are correct. So F is the answer.
