Question

A lady has only 25 paisa and 50 paisa coins in her purse if she has 50 coins in all totalling rupes 19.50 how many coins of each kind does she have?​

Answer 1

Answer:

Let x and y be the number of 50-paisa and 25-paisa coins respectively. Then x + y = 50 ……….(i) 0.5x + 0.25y = 19.50 ………(ii) Multiplying (ii) by 2 and subtracting it from (i), we get 0.5y = 50 - 39 ⇒ y = 11/0.5 = 22 Subtracting y = 22 in (i), we get x + 22 = 50 ⇒ x = 50 – 22 = 28 Hence, the number of 25-paisa and 50-paisa coins is 22 and 28 respectively.Read more on Sarthaks.com - https://www.sarthaks.com/132281/lady-has-only-paisa-coins-and-paisa-coins-her-purse-if-she-has-50-coins-in-all-totaling-rs-19-50
