Question

how many squares must be shaded so that only 30% of the figure is left unshaded

Answer 1

I think 6 squares must be shaded

Answer 2

Answer:

14 squares must be shaded so that only 30% of the figure is left unshaded.

Step-by-step explanation:

To Find: how many squares must be shaded so that only 30% of the figure is left unshaded

Total number of squares in the given figure : 20

Since we are given that 30% of the figure must be left unshaded.

So, $30\% *20$

$\frac{30}{100} *20$

$3*2$

$6$

Thus out of 20 , 6 must be left unshaded.

Thus Squares must be shaded : 20-6 =14.

So, 14 squares must be shaded so that only 30% of the figure is left unshaded.
