Quantitative Aptitude ( CCS) Number System

Geometric mean of the numbers, 4, 8, 16 is

28/7

28/3

none of these

- Geometric Mean Calculation:

- The geometric mean is found by multiplying all numbers together and then taking the nth root (where n is the total number of values).

- For the numbers 4, 8, and 16, multiply them: 4 × 8 × 16 = 512.

- There are three numbers, so take the cube root (n=3) of 512.

- Cube root of 512 is 8.

- Checking Options:

- Option 1: 28/7 = 4 (not the geometric mean).

- Option 2: 28/3 ˜ 9.33 (not the geometric mean).

- Option 3: 8 (matches the calculated geometric mean).

- Option 4: None of these (incorrect as 8 is a valid answer).
