Question

Rohan borrowed Rs 6000 from Kanta for 2 years at a certain rate of interest. If Rohan

paid back Rs 7800 to Kanta , find the rate of interest.​

Answer 1

Answer:

Given, Principal amount lent by Rohit = Rs 60000

R = 10 %

T = 2 years

Interest =

100

P×R×T

=

100

60000×10×2

= Rs 12000

Principal amount borrowed by Rohit = Rs 60000

R = 9 %

T = 2 years

Interest =

100

P×R×T

=

100

60000×9×2

= Rs 10800

Amount gained by Rohit = 12000−10800=1200
