Implementation of whitelists with 3 different discount rates to Etherum Smart Contract

I will create a smart contract. The project is on the TestNet. Token is ERC20 Ethereum token.

I am testing a crowdsale with discount.

Token name is TestXY (TXY)

Example

Normal price rate 100 TXY = 1 ETH

There are 3 different groups on Crowdsale. Group A, Group B, Group C

Group A - %15 discount - 1 ETH = 115 TXY

Group B - %10 discount - 1 ETH = 110 TXY

Group C - %5 discount - 1 ETH = 105 TX

Non Group A,B,C investors - 1 ETH = 100 TX

Each groups have 100 Ethereum Addresses.
