A Tk. 4800

B Tk. 6000

C Tk. 8000

D Data is inadequate

Solution

Correct Answer: Option D

মনেকরি,
আসল = P
মুনাফার হার, r = 8%
সময়, n = 6 বছর
মুনাফা, I = P/2

আমরা জানি,
I = Pnr
বা, P/2 = P × 6 × 8/100
বা, P/2 = 12P/25
বা, (P/2) - (12P/25) = 0
বা, (25P - 24P)/50 = 0
বা, P = 0

∴ সঠিক উত্তর হবে - Data is inadequate.
