F-number of 5 rupee notes
T-number of 10 rupee notes
W-number of 2 rupee notes
.
.

1.5F%2B10T%2B2W=220
.
.
2.T=F%2B6
.
.
3.W=5
Substituting 3 into 1,
5F%2B10T%2B2%285%29=220
5F%2B10T=210
F%2B2T=42
Now substituting eq. 2 into this one,
F%2B2%28F%2B6%29=42
F%2B2F%2B12=42
3F=30
Now solve for F, then use the other equations to solve for T and W.
