Solution

Step: Finding the weight of potato which contains $39 k g$ of water

Given:

$78 %$ of the total weight of potato $=$ Weight of water in a potato.

Let, total weight of potato be $x$ .

Therefore,

$= 78 % \times x = 39 k g$

$= \frac{78}{100} \times x = 39$

$= x = \frac{39 \times 100}{78}$

$= x = \frac{100}{2} = 50 k g$

$= x = 50 k g$

Hence, the weight of potato which contains $39 k g$ of water is $50 k g$ .
