We need to find frequency in the region.

$\\ \sf\longmapsto 50\leqslant l$

We should calculate in it frequencies of below

$\\ \sf\longmapsto 50\leqslant l<60$

$\\ \sf\longmapsto 60\leqslant l<80$

$\\ \sf\longmapsto 80\leqslant l<100$

$\\ \sf\longmapsto 100\leqslant l<150$

Hence

total frequency:-

$\\ \sf\longmapsto 8+b+c+d$
