Answer 1

Answer:

sum borrowed =PTR/100

P=92400

R=15%

T=2

= 92400 x 2 x 15 /100

= 924x2x15

=31860x2

=27720

therefore sum borrowed is 27720

Step-by-step explanation:

Answer 2

compound amount=p(1+r/100)

p(1+15/100)² ruppes

=p(115/100)² ruppes

=p(23/20)² ruppes

=p×23/20×23/20=92400

or,p=92400×20×20/23×23=69868 ruppes (approx)

sum that borrowed=69868 ruppes (approx)
