Question

A sold an article to B at a loss of 20% and B sold it ti C at a profit of 20% If A had sold the article for the price C paid ,what would have been his Los or gain percent

Answer 1

let the cost to A as 100
A sold to B =100-(100×20%)=80
B sold to C =80+(80×20%)=96
if A sold at the price C paid
loss =100-96=4
% of loss=(4÷100)×100=4%
