The average (arithmetic mean) of three positive numbers is 10. One of the numbers is 12. The product of the other two numbers is

MaRussiya [10]

Answer:

Step-by-step explanation:

Let x and y be two numbers other than 12.

We have been given that the average (arithmetic mean) of three positive numbers is 10. We can represent this information in an equation as:

$\frac{x+y+12}{3}=10$

We are also told that the product of the other two numbers is 32. We can represent this information in an equation as:

$x\cdot y=32...(2)$

$x=\frac{32}{y}$

Upon substituting this value in above equation, we will get:

$\frac{\frac{32}{y}+y+12}{3}=10$

$\frac{\frac{32}{y}\cdot y+y\cdot y+12\cdot y}{3}=10\cdot y$

$\frac{32+y^2+12y}{3}=10y$

$\frac{32+y^2+12y}{3}\cdot 3=10y\cdot 3$

$32+y^2+12y=30y$

$y^2+12y-30y+32=30y-30y$

$y^2-18y+32=0$

$y^2-16y+2y+32=0$

$y(y-16)-2(y-16)=0$

$(y-16)(y-2)=0$

$y=2, 16$

Since product of 2 and 16 is 32, therefore, the greatest of the three numbers would be 16.
