Study the bar graph and answer the question. Percentage decrease in the number of trees planted in 2016 in state A as compared to that in 2015 in the same state was:

$15\frac{2}{3}$ $13\frac{1}{3}$ $15\frac{5}{13}$ $13\frac{2}{3}$

$13\frac{1}{3}$

Number of plants planted in 2016 = 78 Number of trees planted in 2015 = 90 Percentage decrease = \(\frac{90 - 78 }{90}\) × 100 = \(\frac{12 }{90}\) × 100 = 13\(\frac{1 }{3}\)
