The ratio of weights of two spheres of different materials is 8 : 17 and the ratio of weights per 1 cc of materials of each is 289 : 64. The ratio of radii of the two spheres is
-
- 8 : 17
- 4 : 17
- 17 : 4
- 17 : 8
- 8 : 17
Correct Option: A
| Ratio of the volumes of spheres = | ||
| 289 × 17 |
| ⇒ | πr1³ | = | |
| 3 | |||
| πr2³ | 17 × 17 × 17 | ||
| 3 | |||
| ⇒ | = |  |  | ³ | ||
| r2³ | 17 |
| ⇒ | = | ||
| r2 | 17 |
