kobusy [5.1K]

Answer: b.14

Step-by-step explanation:

We have two shelves, the top shelf $s_{t}$ and the bottom shelf $s_{b}$ .

Now, firstly we are told the top shelf has 10 more than 1/3 the number of books on the bottom shelf. This can be expressed as:

$s_{t}=10+\frac{1}{3}s_{b}$ (1)

Then, we are told there are 12 books on the bottom shelf:

$s_{b}=12$ (2)

Substituting (2) in (1):

$s_{t}=10+\frac{1}{3}(12)$ (3)

$s_{t}=10+\frac{12}{3}$ (4)

$s_{t}=14$ (5) This is the number of books on the top shelf

Hence, the correct option is b.
