Question

William has bought 30 apples out of which 20% are rotten. Can you write an expression for the apple that are edibles?

• A. $30=6+x$
• B. $30=6-x$
• C. $20=6+x$
• D. $30=5+x$

Answer 1

The correct option is A $30=6+x$

Total number of apples bought = 30
Number of apples rotten$=20\%\text{of}30$
$\Rightarrow \frac{20}{100}\times 30=\frac{600}{100}=6$

Let the number of edible apples be $x$

The total number of apples = Number of rotten apples + Number of edible apples
$\Rightarrow 30=6+x$
