Question

r =3.5 , t =2 years , amount = 535 .find S.I AND P

Answer 1

Given

Principal Amount= P = ?

Rate of Interest Per annum= R= 3.5%

Time = T = 2 years

Amount = 535

We know that

Amount= P(1+TR)

535=P(1 + 2×3.5/100)

535=P(1 + 0.07)

535 =P(1.07)

535/1.008 = P

500= P is the Principal Amount

Simple Interest= Final amount - Principal Amount

= 535 - 500 = 35

Answer 2

p= 500 , si 35 hope it will help you
