The pie charts shows 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,Jack says ‘The pie charts show that Germany won more gold medals than the Russian Federation’. Is Jack correct in his statement? Choose the correct option.

The correct option is A (True)

Let the total medals in the Winter Olympics is x
Given Germany won $7$ Bronze medals.
$\Rightarrow \frac{84}{360}\times x=7$
$\Rightarrow x=\frac{360}{84}\times 7$
$\therefore x=30$
Now, gold sector makes an angle of ${120}^{\circ }$ for Germany.
$\Rightarrow \frac{84}{360}\times 30=7$ gold medals.
Similar way, gold sector makes an angle of ${72}^{\circ }$ for Russia.
$\Rightarrow \frac{72}{360}\times 30=6$ gold medals.
Hence, the Germany won more gold medals than the Russian Federation.
