let the no. of 25 paise coin be r and no. of 50 paise coin be s. no of 25 coin be 4 times 50 paise it means value of r is 4s
Answer :
25 paise × r + 50 paise × s = 30 rupees
25 paise × 4s + 50s. = 3000 paise
100s + 50s = 3000 paise
150s = 3000 paise
s = 3000/150
s = 20
it means that the no. of the 50 paise coin is 20
no. of 25 paise coin = 20 × 4
= 80
