Question

find the principal that will amount to rupees 3752 in 3 years at 12/5 %​

Answer 1

Answer:

amount = principal + simple interest A=P+(p*r*t)/100

=3752=P+(P*12*3)/5*100. - as t=12/5 and =3752=P+(p*36)/500 r=3%

=by taking l.c.m =500

=3752=(500P+36P)/500

=3752*500=536P

=1876000=536P

=1876000/536=P

=P= 3500 ans.

Answer 2

Step-by-step explanation:

a) Given P =1200,R 12%, T= 3years.

We known that SI = P*R*T/100

= 1200*12*3/100

=43200/100

=432.

We known that amout =principal + Interest

=1200+432

=1632.

The amout to be paid = 1632 rupees.

Given P = 7500,R 5%, T=3years

we know that SI = PRT/100

=7500 *5*3/100

=112500/100

=1125.

we know that amount = principal + interest

=7500+1125

=8625.

The amount to be paid =8625 rupees.
