Question

Find the amount to be paid at the end of 3 years on Rs 12000 at 12% p.a.

Answer 1

Step-by-step explanation:

We have,

(a) principal(p)=Rs1200

Rate(R)=12%

Time(t)=3year

S.I=

100

P×R×T

=

100

1200×12×3

=Rs432

amount=P+S.I

=1200+432

=1632

(b)P=7500

rate(r)=5%

T=3year

S.I=

100

P×R×T

=

100

7500×5×3

=1125

amount=7500+1125

=8625

Answer 2

Answer : Principal = ₹ 12000 , Rate = 12% p.c.p.a , Number of years = 3 Simple Interest = P×R×N/100. S.I = 1200×12×3/100. Therefore , simple interest = ₹ 4,320. Therefore , Amount = principal + Interest .... Amount = 12000 + 4,320 = ₹16320........ Therefore , amount to be paid at the end of 3 years = ₹ 16, 320
