1]A towel was 50 cm broad and 100 cm long.When bleached,it was found to have lost 20 percent of its length and 10 percent breadth.The percentage decrease in area is
a] 28 % b] 20% c] 10.08% d] 10%
original area = 100* 50
reduced length = 80% of 100 = 80
reduced breadth = 90% of 50= 45
reduced area = 80*45
reduction in area = 500 - 3600 = 1400
% reduction = [400/5000] 100 = 28 %
a] 28 % b] 20% c] 10.08% d] 10%
original area = 100* 50
reduced length = 80% of 100 = 80
reduced breadth = 90% of 50= 45
reduced area = 80*45
reduction in area = 500 - 3600 = 1400
% reduction = [400/5000] 100 = 28 %
