If the cost of an article is ₹ P after two successive reductions of 20% and 25%, original price of the article was:

₹ \(\frac{5}{3}\) P

S.P. after 1st reduction of 20% = M.R.P. ×\(\frac{80}{100}\) 

S.P. after 2nd reduction of 25% = M.R.P. ×\(\frac{80}{100}\) ×\(\frac{75}{100}\) = P

⇒ M.R.P. = P ×\(\frac{5}{4}\) ×\(\frac{4}{3}\)

⇒ M.R.P. = \(\frac{5}{3}\) P
