Question

Find the missing number.

$6˸24\colon\colon ?˸4$

Answer 1

Given:

$6˸24\colon\colon ?˸4$

Here one mean is missing

$\mathrm{One}\mathrm{mean}=\frac{\mathrm{Product}\mathrm{of}\mathrm{extremes}}{\mathrm{other}\mathrm{mean}}$

$=\frac{6\times 4}{24}$

$=1$

Hence, the missing number is $1$.
