Marks: +1, -0

In a chocolate store, all chocolates are either vanilla or cocoa flavored only.

10 \%

of the chocolates are cocoa flavored,

90 \%

of the rest are squashed.
What percentage of the chocolates are both vanilla flavored and not squashed?

Solution:

Pick a number of chocolates; it is best to take 100 as an example. 10 are cocoa,

90 \%

of the rest

(0.9 × 90=81)

are squashed.
That means that only 9 are both vanilla flavored and not squashed.
