கொடுக்கப்பட்டது:

முதன்மை = ரூ. 8000

விகிதம் = 10%

நேரம் =   \(2\frac{2}{5}\) ஆண்டுகள்

பயன்படுத்தப்படும் சூத்திரம்:

SI = (P × t × r)/100

CI = P(1 + r/100) t - P

பி = முதல்வர்

t = நேரம்

r = விகிதம்

கணக்கீடு:

SI = (8000 × 12 × 10)/(100 × 5)

⇒ ரூ. 1920

CI = 8000[1 + 10/100] 2 × [1 + 4/100] - 8000

⇒ 8000 × 11/10 × 11/10 × 26/25 - 8000

⇒ 10067.2 - 8000

⇒ 2067.2

வேறுபாடு = 2067.2 - 1920 = 147.2

∴ தேவையான வேறுபாடு ரூ. 147.2

குறுக்குவழி தந்திரம் qImage65f494db3692bb77a5668945

எனவே, CI மற்றும் SI இன் வேறுபாடு = 80 + 32 + 32 + 3.2

CI மற்றும் SI இன் வேறுபாடு = 147.2.
