A school girl spends (frac{1}{4}) of her pocket money on books and (frac{1}{3}) on dress. What fraction remains?
-
A.
(frac{5}{6}) -
B.
(frac{7}{12}) -
C.
(frac{5}{12}) -
D.
(frac{1}{6})
Correct Answer: Option C
Explanation
Let the girls pocket money be rep. by x. The amount spent on books = (frac{1}{4}ofhspace{1mm}x = frac{x}{4})
The amount spent on dress (=frac{1}{3} of hspace{1mm}x=frac{x}{3})
∴The fraction that remains = (frac{x}{1}-left(frac{x}{4}+frac{x}{3}right)\
frac{3x+4x}{12}; = frac{12x-7x}{12} = frac{5x}{12} = frac{5}{12})
