all stamps x 6= 120,90,60,42,12
all stamps x 5= 100,75,50,35,10
last 2 of "x6" series cant b there as we want sum to be 300
and 2nd and 4th must b in "x5" series to make 0 in the end
so.......
2 paise,7 paise,15 paise denomination stamps each 5 were bought.
10 paise, 20 paise denomination stamps each six were bought.

5(7+10+2+15+20)=54
54*5=270
300-270=30
i.e. 20+10 extra needed
Hence 6 stamps of 20p and 10p each were bought. 5 stamps of 2p, 7p, 15p each were bought.
