Question

What is the ratio of the shaded area to the unshaded area?

• A. $5:7$
• B. $3:4$
• C. $7:10$
• D. $7:3$

Answer 1

The correct option is D $7:3$

Total number of equal parts $=10\times 2=20$
Number of shaded parts $=14$
So, the number of unshaded parts $=20-14=6$
$\therefore$ Required ratio $=14:6=7:3$.
