Answer:
Eva's sister WAS NOT correct.
The correct ratio is 93 chocolates to 279 non chocolates.
Step-by-step explanation:
The chance of getting chocolate is 1 in 4.
It implies she gets 1 chocolate for every 3 non chocolate.
⇒The ratio of Chocolate : Non Chocolate = 1 : 3
or, we can say that:
Number of non - chocolates = 3 x (Number of chocolates)
Now, Eva received 93 chocolates and 275 non chocolates.
Now here, Number of non chocolates should be 3 x 93 = 279
But she has received 275 chocolates.
⇒ Eva has received 4 chocolates LESS than the desired number.
Hence, Eva's sister WAS NOT correct.
The correct ratio is 93 chocolates to 279 non chocolates.
