Amount = Principal + interest
= 4200 + 882
= Rs 5082
Amount = Principal + interest
= 5000 + 1200
= Rs 6200
Amount = Principal + interest
= 8000 + 800
= Rs 8800
iv. Amount = Principal + interest
∴ 18000 = Principal + 6000
∴ Principal = Rs 12000
Amount = Principal + interest
= 19200 + 2400
= Rs 21600
