മരിയ ജോസഫിൽ നിന്ന് 5% വാർഷിക സംയുക്ത പലിശ നിരക്കിൽ ₹16000 കടം വാങ്ങി. 2 വർഷവും 4 മാസവും കഴിഞ്ഞാൽ അവൾ തിരികെ നൽകേണ്ട തുക എത്ര?

A17640

B17934

C18228

D17943

Answer:

B. 17934

Read Explanation:

P=16000, R=5%, T=2 വർഷം 4 മാസംP = 16000,\ R = 5\%,\ T = 2\ \text{വർഷം}\ 4\ \text{മാസം}

A=P(1+R100)2×(1+4R12×100)A = P(1+\frac{R}{100})^{2} \times \left(1+\frac{4R}{12 \times 100}\right)

A=16000×(1.05)2 A = 16000 \times (1.05)^2

A=16000×1.1025=17640A = 16000 \times 1.1025 = 17640

4 മാസത്തേക്കുള്ള പലിശ=17640×5100×4124\ \text{മാസത്തേക്കുള്ള പലിശ} = 17640 \times \frac{5}{100} \times \frac{4}{12}

=17640×160=294= 17640 \times \frac{1}{60} = 294

ആകെ തുക=17640+294=17934 \text{ആകെ തുക} = 17640 + 294 = 17934
