We have to calculate rate when,
P=Rs630
T=4yrs
Interest=Rs126
We know that,
Interest=Ptr÷100
So,
126=630×4×r÷100
126=126r÷5
126×5=126r
126×5÷126=r
r=5
Hence, rate =5%
P=Rs630
T=4yrs
Interest=Rs126
We know that,
Interest=Ptr÷100
So,
126=630×4×r÷100
126=126r÷5
126×5=126r
126×5÷126=r
r=5
Hence, rate =5%
