Question

A bag contains 25 paise and 50 paise coins who's total value is Rs. 30. If the number of 25 paise coins is 4 times that of 50 paise coins, find the number of each type of coins.

Answer 1

Let number of 25 paise coins = x,

Number of 50 paise coins = y

x/4 + y/2 = 30

x + 2y = 120 …………….(i)

Also x = 4y (given)

Substituting the value of x in eq.(i), we get

4y + 2y = 120

6y = 120

y = 20

So x = 120 - 2y = 120 – 40 = 80

Therefore, number of 25 paise = 80 and number of 50 paise coins = 20.
