A solid toy is in the shape which is a combination of a cylinder, cone and a hemispherical bowl. The cylinder contributes to 50% of the total volume of the toy, the cone contributes to 20% of the volume. Find the ratio of the contribution (in terms of volume) of the cone, cylinder and hemisphere.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 2 : 5 : 3
Explanation:
According to the given question,
Contribution of cyndrical part = 50%
Contribution of conical part = 20%
So, contribution of hemispherical part = 100 - (50 + 20) = 30%
Now, the ratio of contribution (cone : cylinder : hemisphere) = 20 : 50 : 30 = 2 : 5 : 3
Hnece the required ratio is 2 : 5 : 3.
