Question

A supply of food lasts for a week for $25$ families. How long would it last if $5$ more families are to be supplied?

• A. $5days$
• B. $6days$
• C. $\frac{5}{6}$ of a week
• D. $1\frac{1}{5}weeks$

Answer 1

The correct option is C $\frac{5}{6}$ of a week

$25$ families need supply of food for $1$ week

$1$ family need supply of food for $1\times 25$ week

$25+5$ families need supplies of food for $\frac{25}{30}=\frac{5}{6}$ weeks
