Question 1201377
.
On a balance scale, a bag of flour on the left side balances with a 5/6 kg weight and 2/7 of a bag of flour 
on the right side. The weight, in kg, of a bag of flour is

a) 1/2 b) 25/42 c) 6/7 d) 1 1/6 e) 1 17/25
~~~~~~~~~~~~~~~~


<pre>
Let's assume that  "a bag of floor"  is a standard weight  ( like a  "world constant" ).


Then the problem says that  5/7  of a bag of floor weights  5/6  kg.


Hence,  1/7  of a bag of floor weights  1/6  kg

and then a whole bag of floor weights  7/6  kg = 1 {{{1/6}}} kg.    <U>ANSWER</U>     (option d).

Solved.
