Question

Mickey, Minnie and Donald are picking berries. Minnie has picked 7 berries less than Mickey. Donald has picked 3 times as many berries as Mickey. If Minnie has picked 14 berries, how many has Donald picked?
A. 21 B. 35
C. 42 D. 63

Answer 1

Let the number of berries picked by mickey = x
Then,
number of berries picked by minnie = x-7
number of berries picked by donald = 3x
As per the question,
Minnie has picked 14 berries.
i.e. x-7=14
i.e. x=14+7
i.e. x=21

Hence, 
number of berries picked by mickey = x = 21
number of berries picked by donald = 3x = 63.

Therefore the right option is: D.

Hope that helps.
