2000 രൂപ 12.5% പലിശനിരക്കിൽ എത്ര വർഷം കൊണ്ട് 4000 രൂപയാകും?

A5 വർഷം

B8 വർഷം

C12 വർഷം

D7 വർഷം

Answer:

B. 8 വർഷം

Read Explanation:

നിശ്ചിത തുക x വർഷംകൊണ്ട് ഇരട്ടിയാകുന്നതിനാൽ , x = 100/പലിശ നിരക്ക് = 100/ 12.5 = 8 OR SI = PNR/100 SI = 4000 - 2000 = 2000 2000 = 2000 × 12.5 × N/100 2000 = 20 × 12.5 × N 2000 = 250 × N N = 2000/250 = 8
