Mr. Hossain invested n taka at 9% interest

He invested (18,000-n) taka at 10% interest

According to question, (18000-n)×10100+n×9100=1700

= (18000 - n) × 10 + 9n = 170000

=1,80,000-10n+9n = 1,70,000

 n = 180000 - 170000 = 10,000 He invested 10,000 at 9% interest and (18000 - 10000) = 8000 taka at 10% interest. (answer)
