Solution

The correct option is C

10


Given: Germany won 7 bronze medals and angle of the sector = 84

It implies that 84360×total medals=7

Therefore, total number of medals = 7×36084=30 space medals

On observing the graph, we see that the angle of sector for gold medals = 120

So, the number of gold medals won by Germany is 120360×30=10 space medals
