Answer 1

Answer:

Step-by-step explanation:

FIRST WRITE DOWN THE DETAILS

PRINCIPLE=X←(BECAUSE NOT GIVEN)

RATE OF INTEREST=12%PER YEAR

TIME OF PERIOD=3 YEARS

SIMPLE INTEREST=RS 5400

TO FIND THE PRINCIPLE WE WILL USE THE SIMPLE INTEREST METHOD

=SI=PRT/100

=5400=X*12*3/100

WE WILL TAKE 100 FROM RIGHT SIDE TO THE LEFT

=5400*100=36X

=540000=36X

=540000/36=X

=15000

THE PRINCIPLE BORROWED BY HER WAS RS 15000

TO CHECK

=SI =PRT/100

=5400=15000*12*3/100

=5400=540000/100

=5400=5400

VERIFIED OK

HOPE YOU GOT UNDER STOOD
