So there are three variables, rs2 label x, rs5 label y, rs10 label z Lets write equeations using these variables. x+y+z=120 (<span>A bag has a total of 120 notes) 2x+5y+10z=760 (total value) 2x+5*2y+10z=960 (twice as many rs5)
3 variables, 3 independent equations will give solution. There are a fair few ways to solve this. </span>
