Question

Anand cleaned one third of a football ground. 0ne fifthth rest was cleaned by Arun. Asha also cleaned some part. Finally, if 4 of fifteen of total ground was left uncleaned, how much area did Asha clean?

Answer 1

Step-by-step explanation:

$anand \: clean = \frac{1}{3} x$

Remaining 2/3 x

$arun \: clean = \frac{2}{3} \times \frac{1}{5} x$

Asha clean = y

If 4/15 is unclean, total cleaned area = 11/15

$\frac{1}{3} x + \frac{2}{15} x + y = \frac{11}{15} x$

On solving,

$y = \frac{4}{15} x$

Asha cleaned 4/15 th of the area.
