Question

out of 1100 article in a shop 770 article were sold in a week what per cent of article were not sold in that week

Answer 1

hello Frnd

Here is your answer

Total Number of Articles = 1100
Article sold = 770
Remaining Article = 1100 - 770 = 330

Let the % of Articles not sold = X

% of Articles not sold = 1100 × X/100 = 330
11X = 330
X= 330/11
X= 30%

Hence 30% article is not sold
