Step-by-step explanation: The LOAN taken by Rohit =Rs20000. Original rate =10%. Time =3yrs. ∴ The original amount should have been paid =Principal×(1+rate) time
=20000Rs(1+ 100 10
)
=Rs26620.. But he paid an interest @ 10% for 2yrs. ∴The amount after 2yrs. =20000 RS(1+ 100 10
) 2
=Rs24200.. Now he PAYS 15% interest for 1yr. ∴ The amount after 1yr. =24200×Rs(1+ 100 15
) =Rs27830.. So, the extra amount Rohit has to pay =Rs(27830−26620)=Rs1210 |
