Best answer

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
