Question

1. Find the S.I. and the amount on :
(i) 150 for 4 years at 5% per year.
1
(ii) 350 for 3 years at 8% p.a.
​

Answer 1

Step-by-step explanation:

i) SI=P×R×T/100

=150×4×5/100

= 30

A=P+SI

=150+30 or 180

ii)SI=350×3×8/100

=8400/100

=84

A=P+SI

= 350+84

=434

Answer 2

I)Rs.150 for 4 years at 5% per years.

We know that P=Rs.150,

R=5% per years

T=4 years

Here S.I =(P×R×T)/100

Substituting the values =(150×5×4)/100 = Rs 30

Amount =P+S.I

Substituting the values =150+30=Rs.180

ii)

p = 350Rs

R= 8%

T= 3 years

Here S.I =(P×R×T)/100

Substituting the values =(350×8×3)/100 = Rs 84

Amount = =P+S.I

Substituting the values =350+84=Rs.434
