Lorcan has red and green apples.
A quarter of the apples are green.
Lorcan puts the apples in two boxes, A and B
65% of the green apples are placed in box A.
There are 133 green apples are in box B.
Work out how many red apples Lorcan has.

Well the required method is: 100-65=35 so we do 35% of 133 which is 380. We then do 380 multiplied by 3 to get 1140 which is the answer. But why are we multiplying by three where did we get three from? Also is this method and answer correct?
