In a purse there are 20rupee notes 10rupee notes and 5rupee notes. the number of 5rupee notes exceeds two times the 10rupee notes by one. the 20rupee notes are 5 less than the 10rupee notes. if the total value of the money in the purse is Rs185 find the number of each variety of notes.

maths plse help me.. 
PsyDAG,
Let #10rupee = x, then #5rupee = 2x+1 and #20rupee = x5.
x + (2x+1) + (x5) = 185
Solve for x, then the other expressions.
