Question

rupees 15,000 is deposit at simple interest if amount after 8 years is rupees 25,000, find the rate of interest​

Answer 1

Answer:

Let the rate of interest be r%

P = 15000rs

T = 8 years

A = 25000rs

S.I. = 25000- 15000

= 10000rs

S.I. = (PTR)/100

10000= ( 15000×8×R )/100

(10000×100)/(15000×8) = R

25/3= R

R = 8.3%

The rate of interest is 8.3%

hope it helps........

Answer 2

Answer:

9%

25800-15000

=10800

S.I=15000×r×8÷100

=1200

rate=10800÷1200

=9%
