Question

Billy put all his stickers into 30 large albums and 10 small albums. Each large album can hold 10 more stickers than each small album. 1/6 of his stickers were put into all the small album and the rest were put into the large albums. How many stickers can be put into one large album?

Answer 1

If large pages have x stickers, then small pages have (x-10) stickers. So, assuming all the albums were completely filled, then
10(x-10) = 1/6 (10(x-10) + 30x)
x = 25
