hey here is your answer
let the no. 5 coin = X
no. of 2 coin = 3X
no. of 1 coin = 160-(X+3X)
= 160-4X
now according to question..
amount of 1 coin = 1×(160-4x)
amount of 2 coin = 2×3x= 6x
amount of 5 coin = 5×x= 5x
given total amount = 300
so
160-4x+6x+5x=300
160+7x= 300
7x=140
x=20
hence
no. of 1coin = 160-(4×20)=80
no. of 2coin =3×20=60
no. of 5coin= 20
I think my answer is capable to clear your confusion
