Three animals

Ramrao bought a cow, a buffalo, and an ox for a total of Rs 85,000. The ratio of the price of a cow, buffalo, and ox is 4:8:5. What is the price of an ox?

Correct answer:

o =  25000

Step-by-step explanation:

$$\begin{gathered} t=85000 \\ t=c+b+o \\ c:b:o=4:8:5 \\ k=\frac{5}{4+8+5}=\frac{5}{17}\doteq 0.2941 \\ o=k\cdot t=\frac{5}{17}\cdot 85000=\frac{5\cdot 85000}{17}=\frac{425000}{17}=25000 \end{gathered}$$
