Correct answer: D

$2frac{1}{5}+3frac{3}{10}+4frac{2}{5}+5frac{1}{2}$

Convert all the fractions to a common denominator (10):

$2frac{2}{10}+3frac{3}{10}+4frac{4}{10}+5frac{5}{10}$

$(2+3+4+5)+(\frac{2}{10}+\frac{3}{10}+\frac{4}{10}+\frac{5}{10})$

$14+\frac{14}{10}$

$14+1\frac{4}{10}$

$15frac{4}{10}$

$15frac{2}{5}$
