A man bought two cars for Rs 1,30,000each .He sold one car at a profit of 10 % and he another car at a loss of 5%.Find :

1 What is the profit in whole transaction
2 if the man invest the profit made in whole transaction at 10% compounded yearly, then what will be the total sum after 3 years?

Since I'm not sure just what "1,30,000" means,, I'll just use P

0.10P - 0.05P = 0.05P
P*1.05 * 1.10^3 = 1.39755P
