QUESTION: 76

Susan spent one-third of her money on books and half of the remaining money on clothing. She then spent three-fourths of what she had left on food. She had $5 left over. How much money did she start with?

$60
$80
$120
$160
$180

Answer(s): A

Explanation:

Start with the money she had left and work backwards. If she had $5 left over, and had just spent three-fourths of her money on food, then $5 must be one-fourth of her money. Before buying food she must have had 5 × 4 = $20. She then spent half of her money on clothes; therefore, $20 was half of her money, giving her $40 at this point. She then spent one-third of her money on books and had $40 left over. If $40 represents two-thirds of her money, then $60 must be the amount she began with.
