Correct Answer: Option C
Explanation

let the girls' initial pocket money be whole(1)

\(\frac{1}{4}\) of 1 = books, \(\frac{1}{3}\)  of 1 = dress 

fraction of her money left = 1 - \(\frac{1}{4}\) - \(\frac{1}{3}\)

                                   =   \(\frac{5}{12}\)

 

 

There is an explanation video available below.
