Total No of squares = 25
Unshaped = 10

$$\frac{5}{10}*100$$

= $$50$$ %

Thus, answer will be (C) 50%

1) Half of 10 is 5
50 percent of 10 is 5
15 - 10 = 5
15 is 50 percent greater than 10

OR

2) Percent greater than:

$$\frac{New - Old}{Old} * 100$$

$$(\frac{15 -10}{10}) = (\frac{5}{10}) = (.5 * 100)$$ = 50 percent
