The wholesaler purchase the article at Rs.118 and sell it to the retailer at

a price of 118+(118×20/100)=118+118+(118×20/100)=118+

(118/5)=(590+118)/5=708/5(118/5)=(590+118)/5=708/5

The retailer purchase it at Rs. 708/5708/5 and sell it to the customer at a price

of

(708/5)+(708×25/100)=(708/5)+(708/5)+(708×25/100)=(708/5)+

(177/5)=(708+177)/5=885/5=177(177/5)=(708+177)/5=885/5=177

by the given question, 177≡30.09177≡30.09 or, 100≡(30.09/177)×100=17100≡(30.09/177)×100=17
