Question

A dishonest dealer sells articles at 10% loss on cost price but uses the weight of 16 g instead of 18 g. what is his profit or loss per cent?

Answer 1

11/4 % gain

Step-by-step explanation:

Given that a = 10% , b = 16g and c = 18g

= [(100 - a)c /b - 100)]%

= [(100 - 10) x 18/16 - 100]%

= [90 x 18/16 - 100]%

= [90 x 9/8 - 100]%

= 810/8 - 100 %

= (810 - 800) / 8 %

= 10/8 % = 5/4 %

=11/4% gain
