Question : The radius of two spheres is in the ratio of 1 : 5. What is the ratio of the volume of the two spheres?
Option 1: 8 : 27
Option 2: 1 : 25
Option 3: 1 : 125
Option 4: 1 : 64
Correct Answer: 1 : 125
Solution : Let the radii r1 = $k$ and r2 = 5$k$ According to the question, ⇒ Volume of sphere 1 (V1) = $\frac{4}{3}\pi k^{3}$ ⇒ Volume of sphere 2 (V2) = $\frac{4}{3}\pi (5k)^{3}$ = $\frac{4}{3}\pi (125)k^{3}$ ⇒ Ratio of volumes = $\frac{V1}{V2}$
Question : Two vessels of equal capacity, and both completely filled, contain mixtures of milk and water in the ratio of 5 : 1 and 6 : 5, respectively. Both the mixtures are now mixed thoroughly. What is the ratio of milk to water in the new mixture so obtained?
