3/8 of her remaining money = 1/4 of her
original
money
8/8 of her remaining money = 1/4 / 3/8
= 2/3 of her
original money
Therefore 1/3 of her original money was spent on the book.
1/3 = $19.20
2/3 = 38.40

Money spent on pen and stamps
= 5/8 * 38.40 = $24

Price of 1 Pen = price of 2 stamps
1P = 2S
3S = $24
1P = [24/3] * 2 = $16
