A man borrowed some money for 120 days. He asked the banker for the money and the banker charged Tk. 360 as interest @6% per annum. What was the amount he borrowed?
Solution
Correct Answer: Option A
এখানে
সময় n = 120 দিন
= 4 মাস
= 4/12 বছর
= 1/3 বছর
মুনাফা I = 360 টাকা
মুনাফার হার r = 6% = 6/100 = 3/50
আসল P = ?
আমরা জানি
I = Pnr
Pnr = I
P = I/nr
= 360/{(1/3) × (3/50)}
=360/(1/50)
= 360 × 50
= 18000 টাকা
