can anyone solve this? with detailed steps plz.

a seller fixes two prices on his goods- one for ready sale and the other for 6 months credit, interest being calculated at 12.5% per annum. if the credit price per article is rs. 26.56, what is its cash price?

[deepak_dewani]

IF THE RATE IS 12.5% FOR A YEAR, THEN FOR 6 MONTHS IT IS 6.25%. NOW, FOR AN ARTICLE WHOSE READY SALE PRICE IS RS. 100 WILL BE PRICED RS. 106.25 FOR A SIX MONTH CREDIT. HENCE IF THE CREDIT PRICE IS RS. 26.56, IT'S CASH PRICE WILL BE:

(26.56/106.25)*100. DIVIDE BOTH NUM. AND DENOM. BY 13 & U WILL BE LEFT WITH (2.04 /8.17)*100 WHICH IS VERY CLOSE TO 100/4 I.E. 25. HENCE THE READY SALE PRICE IS 25.

IF ANYBODY THINKS THIS IS NOT THE RIGHT SOLUTION, PLEASE REPLY BACK.

NOW THE CALCULATION.
