Answer
Let number of Rs5 coins be x
Number of Rs 2 coins =3× Number of 5 Rs coins =3x
Number of Re1 coins =160−(x+3x)
=160−4x
Amount of Rs5 coins =5×x=5x
Amount of Rs2 coins =2×3x=Rs6x
Amount of Re1 coins =(160−4×x)
=160−4x
As per the question, Total amount =Rs300
160−4x+5x+6x=300
7x=300−160
x=
7
140
x=20
Number of Re 1 coins =160−4x
=160−4×20
=80
Number of Rs2 coins =3x=3×20=60
Number of Rs5 coins =x=20
Answer:
Answer : x=80, y=60 & z=20
