D. 18000​

Answer 1

Answer:

D 18000

Step-by-step explanation:

1st Case

Principal =15000

Rate of interest =12%

Time =2yrs

Interest =PRT/100

=15000×12×2/100

=3600

Now total interest paid =9000

Interest payable on 2nd Amount =Total interest - Interest paid on 1st amount

=9000-3600

=5400

let the 2nd principal amount be X

rate of interest =15%

time = 2 yrs

Interest =PRT /100

5400=X×15×2/100

5400×100/15×2 =X

18000 =X

Hence Second amount borrowed is 18000
