Question

2. A publishing house hed 40% of its total sales in Math books, 10% in pupil diary, 20%

in Filipino books, 20% in Science books and 10% in English books. If the sales

amounted to P1,250,000.00 find the total sales in each kind of book. What book had

the least sales

Solution:

Answer 1

$$40+10+20+20+10=100(\%)$$

$$\begin{matrix} 1250000.00 & 100\% \\ x & 1\% \end{matrix}$$

$$x=\dfrac{1250000.00(1)}{100}=12500.00$$

Math

$$12500.00(40)=500,000.00$$

Pupil diary

$$12500.00(10)=125,000.00$$

Filipino

$$12500.00(20)=250,000.00$$

 Science 

$$12500.00(20)=250,000.00$$

English 

$$12500.00(10)=125,000.00$$

Pupil diary books and English books had the least sales.
