Question

How many squares need to be shaded to cover $75\%$ of the total area

• A. $54$
• B. $56$
• C. $60$
• D. $72$

Answer 1

The correct option is A $54$

From figure, Total no. of boxes=$72$

Total area = Total no. of boxes's area

$75$% of total area = $75$% of total no. of boxes

=> $\frac{75}{100}\times 72$

=> $54$
