Question 22

The per cent that represents the unshaded region in the figure, is

(a) 75 %
(b) 50 %
(c) 40 %
(d) 60 %

Answer 1

Given, total parts $=10\times 10=100$
$\because$ Shaded parts = 60
$\therefore$ Per cent of shaded parts = $\frac{60}{100}\times 100\%=60\%$
Then, per cent of unshaded parts = 100 - 60 = 40 %
Hence, the unshaded region is 40 %
