Answer:No of 25 Paise coins=80
No of 50 Paise coins=20
Step-by-step explanation:
Let, no. of 25 Paise coins be x
and no. of 50 Paise coins be y
A.T.Q.
x=4y -------(i)
and 25x + 50y=30×100 Paise
25x + 50y=3000 --------(ii)
Substitute value of x in eq(ii)
25(4y) + 50y=3000
100y + 50y=3000
150y=3000
y=20
Substitute value of y in eq(i)
x=4×20
x=80
No of 25 Paise coins=80
No of 50 Paise coins=20
