Question

15. Ashu had to paint a wall. He finished painting 15%
of the wall. Kamal came and painted 20% of the
remaining wall. What percentage of the wall is still
unpainted?​

Answer 1

$\huge\star\underline\mathfrak\red{Answer:-}$

% means out of 100

So total needed to paint is 100%

100%-(15% + 20%) = %of unpainted wall

. = (100-35)%

=65% is left unpainted
