Principal = ₹ 5,000
Time = 1 yr
Rate (1st case )= 4 %
Rate (2nd case )= 7.4 %
Simple interest in the 1st case =\frac{\text { Prt }}{100}
= ₹ \frac{\text { 5000×4×1 }}{100}
= ₹ 200
Simple interest in the 1st case =\frac{\text { Prt }}{100}
= ₹ \frac{\text { 5000×7.4×1 }}{100}
= ₹ 370
Interest saved = ₹ 370 – ₹ 200 = ₹ 170
