When the price of an article is reduced by 5/8 of its former value, the number of article sold is increased to 32/27 of the original amount. The present daily revenues is what fraction of the original?

Answer 1

n sold originally at p

32 n/27 sold later at 5 p/8

original rev = n p

final rev = (32/27)(5/8) n p

so
(32/27) (5/8) = 20/27
