**Reiny**, Friday, August 23, 2013 at 8:33amlet the amount he started with be x

after first round he has 2x-P

in 2nd round he tripled that and gave away 2P

so has left

6x - 3P - 2P = 6x - 5P

in 3rd round he quadrupled the amount and gave away P

so he has left

24x - 20P - P = 24x - 21P

amount given away = P + 2P + P = 160

P = 40

but at the end he has nothing left, so

24x - 21P = 0

24x - 21(40) = 0

x = 35

**He started with RS 35**

check:

in first round: doubled , gave away P

70-40 = 30

in 2nd round: tripled, gave away 2P

90 - 80 = 10

in 3rd round: quadrupled , gave away P

40 - 40 = 0

my solution checks out.
