Arman wanted to have Tk. 39,200 as interest after 5 years. He has invested an amount in an account for 1 year at 8% interest rate. From the 2^nd year he invested the principal amount in another account offering 10% interest for 3 years.

ক) Tk. 50,000 খ) Tk. 80,000 গ) Tk. 90,000 ঘ) Tk. 70,000

ব্যাখ্যা (Explanation)

মনে করি, Principal = P
Now, 8% এ interest = P x 1 x 0.08 = 0.08P
10% এ interest = P x 3 x 0.10 = 0.30P
11% এ interest = P x 1 x 0.11 = 0.11P
Now, 0.08P + 0.3P + 0.11P = 39200
⇒ P = 39200/0.49 = 80000
