A baker used 40% of a 50kg bag of flour. If \(\frac{1}{8}\) of the amount used was for the cake, how many kilogram of flour was used for the cake?
-
2\(\frac{1}{2}\)
- 6\(\frac{1}{2}\)
- 15\(\frac{3}{8}\)
- 17\(\frac{1}{2}\)
The correct answer is: A
Explanation
\(\frac{40}{100} \times 50\)kg = 20kg\(\frac{1}{8}\) of 20kg for cake; \(\frac{1}{8}\) x \(\frac{20}{1}\)
= 2\(\frac{1}{2}\)kg
