രാമൻ 5,000 രൂപ ഒരു ബാങ്കിൽ 2 വർഷത്തേക്കു 12% സാധാരണപലിശ നിരക്കിൽ നിക്ഷേപിച്ചു. രവി ഇതേ ബാങ്കിൽ 5,000 രൂപ കൂട്ടുപലിശയിനത്തിൽ 2 വർഷത്തേക്കു നിക്ഷേപിച്ചു. രണ്ട് വർഷത്തിനു ശേഷം രവിക്കു ലഭിക്കുന്ന അധിക തുക എത്ര?

A1273

B72

C80

D720

Answer:

B. 72

Read Explanation:

കൂട്ടുപലിശ
---------------

തുക = P[1+R/100]^n

P = 5000

R = 12

n = 2

= 5000[1+12/100]²

= 5000 × 112/100 × 112/100

= 6272

സാധാരണ പലിശ
------------------------

പലിശ  I = PNR/100

P = 5000

R=12

N=2

പലിശ = 5000 × 12100\frac{12}{100} x 2

=1200 

ലഭിക്കുന്ന തുക = 5000 + 1200 = 6200

കൂട്ടുപലിശയുയുടെയും സാധാരണ പലിശയുടെയും വ്യത്യാസം = 6272 - 6200 = 72
