Answer 1

Answer:

Step-by-step explanation:

SIMPLE INTEREST=P×R×T÷100

SIMPLE INTEREST=3450×3×2÷100

SIMPLE INTEREST=20700÷100=207

SO

∴SI=207

AMOUNT=PRINCIPAL(1+R÷100)²

               =3450(1+3÷100)²

               =3450(103÷100)²

               =3450(103÷100)(103÷100)

               =69×103×103÷200

               =732021÷200

AMOUNT=3685.105
