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
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.
