Find the interest on ₨12,000 at 8% p.a. for 4 years.
Given:
Principal =₨12,000
Rate of Interest =8% p.a
Time=4years
We know that
Simple interest =P×R×T100
Then,
Simple interest =12000×8×4100 =120×8×4=3840
Hence, the interest is ₨3840.
The simple interest on a certain sum for 5years at 8%p.a. is Rs200less than the simple interest on the same sum for 3years and 4months at 18%p.a.find the sum.
