(i) 5700 in 3 years at the interest rate of 4% per annum.
lii] 313 875 in 5 years at the interest rate of 6% per annum.​

Answer 1

Answer:

(1), 47500 rs

(2), 1046250 rs

Step-by-step explanation:

4. (1). Given,

Simple interest, S.I= 5700

number of years ,n =3

rate,r= 4

sum of money= principle amount,P=?

SI= Prn/100

5700=(P*4*3)/100

5700=12P/100

5700*100=12P

P=(5700*100)/12=47500rs

(2) Given,

Simple interest, SI= 313875

Number of years,n=5

rate, r= 6

sum of money,P=?

SI=Prn/100

313875=(P*6*5)/100

313875=30P/100

313875*100=30P

P=31387500/30

=1046250rs
