Hey !!
Principal = 450
Rate of interest = ?
Time = 7/2 years.
Simple interest = 189.
We know that,
S.I = P × R × T / 100
189 = 450 × R × 7/ 100 × 2
189 = 3150R/200
3150R = 189 × 200
3150R = 37800
R = 37800/3150
R = 12%
Hence,
Rate of interest = 12%
Principal = 450
Rate of interest = ?
Time = 7/2 years.
Simple interest = 189.
We know that,
S.I = P × R × T / 100
189 = 450 × R × 7/ 100 × 2
189 = 3150R/200
3150R = 189 × 200
3150R = 37800
R = 37800/3150
R = 12%
Hence,
Rate of interest = 12%

Simple interest = 189.
We know that,
S.I = P × R × T
189 = 450 × R × 7/2
189 = ( 225 × R × 7 )
1575R = 189
R = 8.3 %
