Answer 1

25Paise Coin 22 and 50 Paise Coin 28

Answer 2

Step-by-step explanation:

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
