The ratio of three numbers is 3 : 6 : 8. If their product is 9216, then what is the sum of the three numbers?
Let the numbers be $$3x,6x$$ and $$8x$$
Product = $$3x\times6x\times8x=9216$$
=> $$x^3=\frac{9216}{144}=64$$
=> $$x=\sqrt[3]{64}=4$$
$$\therefore$$ Sum of the numbers = $$3x+6x+8x=17x$$
= $$17\times4=68$$
