Hint. If there is 1 blackjack how many sweets are in the bag? What if there are 2 blackjacks, or 3?
I was looking back at some basic questions and I couldn't figure it out... I know the answer but not how it is done (back of the book)
Two bags of sweets each contain blackjacks and fruities
There are fewer than 50 sweets in Bag A
5% of the sweets are blackjack
Write down all possible values for the number of sweets in bag A
(2 marks)
It is not clear whether 5% is counted from the number of sweets in bag A or from the total in both bags. If it's in bag A, then the second bag is irrelevant to the question (but maybe there are other parts of the problem). If it's the total, then there is not enough information.
Assuming 5% is counted from the number of sweets in bag A, find all numbers less than 50 such that 5% of that number is an integer.
