Question

Find the missing number.

$?˸4\colon\colon 49˸28$

Answer 1

Given:

$?˸4=49˸28$

Here one extreme is missing.

$\mathrm{One}\mathrm{extreme}=\frac{\mathrm{Product}\mathrm{of}\mathrm{means}}{\mathrm{other}\mathrm{extreme}}$

$=\frac{4\times 49}{28}$

$=7$

Hence, the missing number is $7$.
