Question

The pie charts show some information about the numbers of medals won by Germany and by the Russian Federation in the 2010 Winter Olympics.

While Germany won 7 bronze medals, how many silver medals did they win?

• A. 10
• B. 15
• C. 13
• D. 20

Answer 1

The correct option is C

13

Given: Germany won 7 bronze medals and angle of the sector = 84${}^{\circ }$

It implies that $\frac{84}{360}\times \text{total medals}=7$

Therefore, total medals won = $\frac{7\times 360}{84}=30$medals.

On observing the graph, we see that the angle of sector for silver medals = 156⁰

So, the number of silver medals won by Germany is $\frac{156}{360}\times 30=13$ medals.
