Question

There are 38 coins in a collection of 20 paise coins and 25 paise coins. If the

total value of the collection is ₹8.50, how many of each are there?​

Answer 1

Step-by-step explanation:

Let the number of 20 paise coins be X

therefore number of 25 paise coins= (38-x)

Equation:

20(x) + 25(38-x) = 850 paise

20x + 950 - 25x =850

20x - 25x = 850 - 950

-5x = - 100

5x= 100

x= 100/5

x= 20

Answer:- Number of 20 paise coins = 20

Number of 25 paise coins = (38-20)=18
