Answer 1

Step-by-step explanation:

first case

from the question

principal is 30000

interest is 9000

time is 3 year

rate=?

r=100*I/p*t

r=100*9000/30000*3

r=10 percent

2nd case

interest=p*r*t/100

p=7500

t=3 year

r=same as last question that is 10 percent

interest=7500*10*3/100

interest =2250

so... amount =p+i

=7500+2250

=9750 ruppee answer
