Answer 2

Answer:

Let number of Re 1 coins = x and number of Rs 2 coins = y Now, by given conditions: Total number of coins = x + y = 50 …(i) Also, Amount of money with her = (Number of Re 1 x1) + (Number of Rs2 x coin 2) = x(1)+ y(2) = 75 = x+2y = 75 …(ii) On subtracting Eq. (i) from Eq. (ii), we get (x + 2y) - (x + y) = (75 - 50) So, y = 25 Putting y = 25 we get x = 25. Hence he has 25 Re 1 coins and 25 Rs 2 coins.Read more on Sarthaks.com - https://www.sarthaks.com/878704/aruna-has-only-and-coins-with-her-the-total-number-coins-that-she-has-the-amount-money-with-her
